CMOS NOR Gate Circuit

CMOS NOR Gate Circuit: Fig. 3.4 shows 2-input CMOS NOR Gate Circuit. Here, P-channel MOSFETs Q1 and Q2 are connected in series and N-channel MOSFETs Q3 and Q4 are connected in parallel. Like NAND circuit, this circuit can be analyzed by realizing that a LOW at any input turns ON its corresponding P-channel MOSFET and turns OFF …

Half Subtractor and Full Subtractor Circuit

Half Subtractor and Full Subtractor Circuit: Subtractor are divided into two categories namely, half subtractor and full subtractor circuit. Half Subtractor Circuit: The Half Subtractor Circuit consists of four possible elementary operations, namely, In all operations, each subtrahend bit is subtracted from the minuend bit. In case of second operation the minuend bit is smaller …
