DESIGN OF A COMPARATOR USED IN I/O UNITS OF INTEGRATED CIRCUITS FOR A 14-NAM COMPLEMENTARY METAL-OXIDESEMICONDUCTOR TECHNOLOGICAL PROCESS

Abstract

In order to have high data transfer speeds, it is necessary to develop receiving and transmitting systems. Receiving and transmitting systems can transmit those speeds without a loss of data. Electromagnetic fields cause noise on transmission lines with uncoordinated wave resistance, and the network of these noises can disrupt the proper operation of the device.As we know, a comparator is an integral part of receiving and transmitting devices designed to compare two analog signals. We give an analog signal at the input of the circuit and receive a digital one at the output. Thus, a comparator can be thought of as an element that performs transitions from an analog signal to a digital one, that is why, it is often referred to as a one-bit analog converter. The comparator has many parameters. These include speed, power consumption, sensitivity, threshold voltage, etc. High-speed comparators allow to get a maximum speed while they take up less space. It is suggested to design a clocked comparator for the 14-nm CMOS technological process, which will have an input sensitivity of 4 mV at a clock rate of 3 GHz. During the research, one scheme wasobserved, parametric optimization wasperformed through the SPICE model, physical modeling was performed using Custom Compiler. The results were displayed and measured using WaveView.
