the SNR requirement, SNR of simulation is 80.27dB.

Engine Controller For A 12-Cylinder 6-Speed Car (Group project) Apr 2012

● Requirements: Design a circuit to control the 12 cylinders and gears of a car. The circuit includes inputs

block, auto-pilot diagram turn-on decision block, RPM/gear control block and cylinders/gears block. I am

responsible for part of RPM/gear control block.

● Results: For the car goes down a ramp, control the cylinders and gears according to the logic given to

maintain the same speed. Mainly use adders, sub-tractors, comparators, multipliers, MUXs and dividers.

VLSI Phase-Locked Loop Circuit Design (Group project) Dec 2012

● Requirements: Design a PLL which is programmable to two frequencies for HS-G2(A/B) applications with

0.18um TSMC technology. Input reference clock at 26.00MHz, output clock at 2.496GHz/2.912GHz, 1MHz

bandwidth. PLL includes PFD, LPF, VCO and frequency divider. I am mainly responsible for frequency divider.
