Laboratory 1: Mixed-signal Simulation Method
In this laboratory you will study to use Cadence Analog Artist to simulate mixed mode circuits. A comparator and a DAC with ahdl description, an encoder with verilog description will be designed and simulated. An 5 bits Flash ADC will be constructed with above parts. Homework 1. Read the text on Full-flash ADC (pp. 121). 2. 3. Review the knowledge of digital simulation in Digital Konstruktion. For a full-flash 5-bits ADC with the input range (± 500 mV ), calculate the number of reference voltages needed and its 1/2 LSB value. For 5 bit accuracy, calculate the minimal threshold voltage of the comparator.
