Title: Improvements in or relating to electrical oscillators
IPC: H03B5/20
Filed: 1960-01-11
Abstract: 910,794. Valve oscillating circuits. WAYNE KERR LABORATORIES Ltd., and LEVINGE, R. W. Jan. 6, 1961 [Jan. 11, 1960], No. 983/60. Class 40 (6). An oscillator consists of three or more integrators connected in series and having a feedback loop to maintain the circuit in oscillation. In the sine wave oscillator of the drawing accompanying the Provisional Specification four integrators 10, 11, 12, 13 are connected in series, each integrator consisting of a high-gain amplifier 14 with a feed-back capacitor 15 and an input resistor 16. The output of the first and third integrators 10 and 12 are combined in an adding unit 20 consisting of an amplifier 21 having feed-back resistor 22 and two input resistors 23, 24. This combined signal is then fed together with the outputs of the second and fourth integrators 11 and 13 to a second adding unit 25 comprising an amplifier 26 with input resistors 27, 28, 29, the resistor 29 being shunted by a resistor 33 in series with a pair of back-toback Zener diodes 31, 32 to limit the amplitude of oscillation. The frequency of the oscillator can be varied by switching the capacitors 15, fine adjustment of frequency can be carried out by adjusting the value of resistors 22, 23, 24, 27, 28. Five pairs of potentiometers 40-49 are used to provide sine wave outputs of differing phase from the oscillator. The non-sinusoidal oscillator, Fig. 2, comprises four integrators 100-103 connected in series, each integrator comprising an amplifier 104 with an input resistor 105 and feed-back capacitor 106, the last three integrators 101-103 having a clamp 107 across capacitors 106 which by application of a control potential can discharge the capacitors 106. The output of integrator 103 is fed to a comparator 108 comprising a mono-stable multivibrator which is triggered from its normal state when the output amplitude exceeds a certain level, this level being such that the integrator does not saturate. The pulse the multivibrator supplies is used to discharge the capacitors via the clamps 107 and also is supplied to the input of amplifier 110, the second input being an inverted output from integrator 100, so that the resultant output from the amplifier is a short pulse 3(a). The resulting output from integrator 100 is a step function 3(b), the output of 101 is a linear ramp function 3(c), the output from the third being a time squared function 3(d), and in general the output of the nth integrator in the chain will be a function v=Vt<SP>(n-1)</SP>. If the required function needs a symmetrical waveform, the clamps are not used, the comparator operates on the rise of output level and the polarity of pulse is reversed so that the output function runs down, so giving a symmetrical waveform. Specification 910,793 is referred to.

IPC: H01L21/822
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a designing method in which data is not broken down due to increase of wiring, increase in signal delay and a clock skew when a scan chain connection is performed. SOLUTION: In a designing method for a semiconductor integrated circuit, a pair of scan registers which perform a scan chain connection are selected (SA4). Then, the straight-line distance on hardware between respective output terminals of scan registers at a previous stage and scan data input terminals of scan registers at a later stage is computed (SA5). In addition, on the basis of a computed result, the output terminal of the scan register at the previous stage, in which the straight-line distance becomes minimum, is selected (SA6), and the connection of the selected output terminal to the scan data input terminal of the scan register at the later stage is decided (SA7). Then, in every pair of scan registers, a scan chain connection is performed by using the decided output terminal (SA8).

Title: Semiconductor integrated circuit
Inventor: KAGA HIROSHI
IPC: G01R31/3185
Filed: 1993-01-07
Abstract: PURPOSE:To reduce or remove restriction to the number of simultaneous operations of emitter coupling logic (ECL) output buffers at the time of testing an integrated circuit by reducing the output logical amplitude of the ECL output buffers at the time of testing the integrated circuit as compared with its practical use. CONSTITUTION:A constant current source for the ECL circuit is constituted of the 3rd and 4th resistors R3, R4 and the resistor R4, one of them, can be separated from the circuit by the 4th MOS transistor(TR) Q4. In the case of practically using the integrated circuit, the TR Q4 is turned on by impressing high potential to a mode switching terminal 4. In the case of testing the integrated circuit, the current value of a current flowing into the constant current source for the ECL circuit is reduced by turning off the TR Q4. Consequently the low output level side is shifted to the high level side as compared with its practical use and the output logical amplitude can be reduced.
