Title: Clamp circuit
Inventor: FUKINUKI NORIHIKO
IPC: H04N5/16
Filed: 1983-07-13
Abstract: PURPOSE:To always make a period where the output value of an analog/digital converter is equal to a minimum level constant value by increasing a DC level when the result of applying analog/digital conversion to a waveform of a specific part is smaller than a predetermined value and decreasing the level in other cases by the control. CONSTITUTION:A minimum level detecting circuit 13 brings its output to a high level during a period only when an output value of the analog/digital converting circuit 2 is equal to the minimum level and brings its output to a low level during other periods. Since a diode 14 is conductive during the period of high level, a potential of a capacitor 16 is increased by a time constant decided by a resistor 15 and a capacitor 16, and the DC level of a clamp signal Vc is increased through a resistor 18. Since the diode is nonconductive during the low level, the DC level is descended by the time constant decided mainly by a resistor 17 and the capacitor 16. That is, when the DC level of the Vc is descended, the period o of the output value of the analog/digital converting circuit 2 is equal to the minimum level is made longer.

Filed: 1980-09-16
Abstract: PURPOSE: To realize a high gain and a wide band, by connecting a cascode circuit consisting of N channel MOSFETs and a cascode circuit consisting of P channel MOSFETs to a CMOS structure.  
     CONSTITUTION: The cascode circuit consisting of a pair of MOSFETs of the same polarity has large output resistance in comparison with a circuit of a single MOSFET, and what is called a linear region is very narrow. Therefore, N channel and P channel cascode circuits are connected similarly to a CMOS inverter; and if the P channel cascode circuit is handled as a load of the N channel cascode circuit, the input voltage determines the voltage between the gate and the source of each polarity identically. Thus, the increment ΔV of the input voltage, the N channel shows a characteristic of increment ΔV 2  and the P channel shows a characteristic of reduction ΔV 2 . Consequently, the input and output transfer characteristic becomes linear.
