CONSTITUTION:An input signal S3 is inputted sequentially to an FF 2 based on a clock signal S2 from an FF 4 inputting and frequency-dividing an output signal S1 of a VCO 17 into 1/2, and an output signal S4 of the FF 2 is fed to an EOR circuit 5 and the FF 3. The input ...
First, consider that a pair of transistors in a differential circuit are functionally equivalent to a transconductance amplifier: voltage input controls a current output. This is a good model for the differential pair, M1 and M2, in your circuit. simulate this circuit –Schematic c...
Another plot twist was running out of time to order a PCB, which required designing one using MS Paint and etching it at home. The demo video below shows the circuit at work, taking the BCD output of a 74HC393 counter — clocked by a 555, naturally — and driving a seven-segment ...
and a comparison circuit that compares the sum of drain currents of the first and fourth transistors with the sum of drain currents of the second and third transistors and thereby determines whether a difference between the first input voltage and the second input voltage is greater or smaller th...
The power-fail input is constantly compared with an internal voltage reference of 1.25 V (see Figure 4: "Power-fail comparator circuit"). If the input voltage falls below 1.25 V, the power-fail output goes low. When it later goes above 1.25 V, the output returns high. Adding two ...
FIG. 1 is a schematic illustration of one embodiment of a prior art digital comparator circuit using a combination of "EXCLUSIVE OR" (XOR) and OR gates. FIG. 2, which is broken into segments (FIGS. 2A and 2B), illustrates one embodiment of a main portion of a fast comparator circuit ...
A new voltage-mode comparator circuit for use in CMOS multiple-valued logic circuits is introduced. Existing comparator circuits for this application use s... YB Guo,KW Current - International Symposium on Multiple-valued Logic 被引量: 25发表: 2002年 Low voltage comparator for High speed ADC Th...

difference represented by the differential input as the offset current, the slave comparator circuit having the same configuration as the master comparator circuit, wherein each of the master and slave comparator circuits receives the associated differential input at respective parallel gates of p-...
Figure 15 also shows one application circuit using this comparator for battery voltage comparison. After using the superposition principle and fill the components value into the spreadsheet the battery voltage threshold is 9.45 V for rising edge and 8.99 V for falling edge. CMPIN RS RDOWN 50kΩ...
