Abstract
Analog-to-digital converters are extensively used for digital signal processing. In this paper, a 4-bit servo tracking type ADC is designed to convert the analog signal to a digital signal. The amplitude range of the analog input signal is 0 to 1 V. Verilog code is designed and simulated in Makerchip IDE for a 4-bit up-down counter circuit. The 4-bit up-down counter along with SKY130 PDK (Process Design Kit) components like resistors and op-amps are used in the circuit design. The 4-bit binary input is converted to analog output using an R-2R ladder type DAC (Digital to Analog Converter). The circuit is simulated in the eSim EDA tool developed by IIT Bombay.
