IPC: H03F3/68
Filed: 1983-07-20
Abstract: A preamplifier contains first to fifth amplifiers (24,25,26, 28, 29) and a selection switch (31). The first amplifier (24) for high frequency band amplification has a low input impedance circuit (24a). The second amplifier (25) for low frequency band amplification has a high input impedance circuit (25a). Either of the first and second amplifiers can provide a path forthe neutron flux level signal derived from a detector (20) according to the frequency of the neutron flux level signal. The third amplifier (pulse amplifier) (26) amplifies the output signal of the first amplifier and transfers the amplified signal to a pulse signal counting system (27). The lower frequency band Campbell signal is applied to the Campbelling system (30), through the second amplifier (25). the fourth amplifier (low frequency band Campbelling amplifier) (28), and the selection switch (31). The higher frequency band Campbell signal is applied to the Campbelling system (30), through the first amplifier (24), the fifth amplifier (high frequency band Campbell amplifier) (29), and the selection switch (31).

Abstract: Dans un procédé de formation d'une structure CMOS (semiconducteur complémentaire d'oxyde métallique) dans un substrat de silicium, des portes de polysilicium (27N, 27P) sont prévues pour des dispositifs à canaux n et des dispositifs à canaux p. Ensuite les régions des dispositifs à canaux p sont protégées par un photomasque tandis que l'arsenic est implanté dans les régions de polysilicium sans masque (27N) et les régions de source/drain de type n (29S, 29D). Au cours d'une étape ultérieure, le silicium dopé à l'arsenic acquiert une couche d'oxyde relativement épaisse (30N) qui est utilisée comme un masque pour les régions de dispositifs à canaux n au cours d'une implantation ultérieure de type p des régions de source/drain de type p (31S, 31D). Une couche intermédiaire d'oxyde (33) ayant des ouvertures est prévue pour être en contact avec des zones du substrat, et une couche de polysilicium (35) est placée par dessus. Pendant que les régions de dispositifs à canaux p sont recouvertes avec un photomasque, de l'arsenic est implanté dans la couche de polysilicium non masquée (35). Durant le chauffage dans une atmosphère d'oxydation, une nouvelle couche oxyde de masquage (37N) est formée et masque les régions de dispositifs à canaux n lors d'une implantation ultérieure de bore dans les régions de contact de type p. Dans une étape ultérieure, les régions de contact des deux types n et p (39S, 39D; 41S, 41D) acquièrent un niveau de dopage accru. Finalement, des conducteurs de contact en aluminium (42) sont prévus sur le polysilicium (35) au-dessus des régions de contact (39S, 39D; 41S, 41D). Le procédé permet une fabrication simple de contacts fiables pour des dispositifs CMOS de dimension réduite.

Abstract: The invention concerns a method for the measurement of capacitances, in particular of low capacitances, in which method a measurement oscillator (10) is used, whose output frequency (f) is a function (f = F(C in )) of the capacitance (C in ) to be connected to the input terminals (a, b) of the circuit determining the frequency of the said oscillator. In the method, a known reference capacitance (C R ) is used, which is connected, being alternatingly exchanged with the capacitance (C M ) to be measured, to the input terminals (a, b) of the measurement oscillator (10) while making use of a switching arrangement. The capacitance to be measured (C M ) and the reference capacitance (C R ) are connected, alternatingly one after the other, to the input terminals (a, b) of the same said measurement oscillator (10) for the time (T, and T 2 ) of an equal number (N) of cycles (T = 1/f) of the measurement oscillator (10). The frequency (f) dependent on the capacitances (C o , C R , C M ) connected to the inputterminals (a, b) of the measurement oscillator (10) is passed to a distributor (11), whose distribution ratio (N) directly determines the number (N) of the said switching cycles. The square wave (V in ) obtained from the output (d) of the said distributor (11) is used for controlling the switches (k 1 , k 2 ) which, while alternatingly exchanging them, connect the known reference capacitance (C R ) and the capacitance (C M ) to be measured, each in its turn, to the input terminals (a, b) of the measurement oscillator (10), so that an exchange of the level of the said square wave (V in  produces an operation of the said switches (k 1  k 2 ) in such a way that the capacitance (C M ) to be measured that is the next one in the sequence is connected in place of the reference capacitance (C R ) and vice versa. The invention also concerns the use of the method in radiosondes, in telemeter measurement of pressure, temperature and/or humidity. By means of the invention, and accurate measurement circuit is obtained by means of which the effects of switching phenomena can be eliminated.

Abstract: The invention relates to a method for detecting ionising current in an ignition circuit (32,33) included in the ignition system of an internal combustion engine, where a measuring voltage is applied to the ignition circuit and a measuring device (29) is utilised for detecting ionising current possibly present in the ignition circuit.In known solutions of this kind, it has been necessary to use comparatively expensive electronic components, usually not manufactured as standard, to protect the outside voltage source from high voltages occurring in the ignition circuit. The problems are aggravated when the prior art is applied to capacitative ignition systems. The present invention solves the problems involved in an advantageous manner and is essentially distinguished in that a constant measuring voltage is applied to the earthed connection (36-39) of the ignition circuit (32,33) between a secondary winding (36-39) of the ignition circuit (32,33) between a secondary winding (30,31) in the ignition circuit and a capacitor (40) in the earth connection, and in that a possible ionising current in the ignition circuit is detected in means (50), by a signal representing the ionising current being taken off from the earth connection of the secondary winding.
