This project shows the design of a frequency synthesizer PLL system that produces a 1.92 GHz signal with a reference input of 30 MHz, with a comparison between using an LC VCO and using a Ring VCO.

The codes are used to generate the VerilogA code which can be directly used in the spectre simulation .The generated VerilogA code's fuction is to generate the specific waveforms according to your setting.And the setting is done in the python code (main.py), which will facilitate greatly the coding works.

This project shows how to model a 10-bit pipeline ADC and a 10-bit DAC using ideal components. Used vdc, vpulse, vcvs, switch, res, cap, vccs to construct the 10-bit ADC based on 1-bit per stage pipelined architecture. Models are built in Cadence using ideal components & VerilogA blocks, & Analysis is done on Matlab.

This project shows how to model a 4-bit flash ADC and a 4-bit DAC using ideal components. Used vdc, vpulse, vcvs, switch, res, cap, vccs to construct the 4-bit ADC based on the flash architecture. Models are built in Cadence using ideal components & VerilogA blocks, & Analysis is done on Matlab.
