The half subtractor is a combinational circuit which is used to perform subtraction of two bits. Half subtractor full subtractor. The output will be difference output of full subtractor.
In the recent years various approaches of cmos 1 bit half subtractor and full subtractor design using various logic styles have been presented and unified into an integrated design policy which shows more delay and consumes more power.
The main difference between a half subtractor and a full subtractor is that the full subtractor has three inputs and two outputs. Since it neglects any borrow inputs and essentially performs half the function of a subtractor it is known as the half subtractor. The borrow part of the full subtractor is a superposed light wave which is a constant signal 3a cos ωt ф if ф 0 it represents 1 output and if it is then it represents 0. The recital estimation of 1 bit half subtractor and full subtractor is based on delay and power consumption.
