Abstract :
This paper discusses the design of a ripple-folding analog to digital (A/D) converter in the current mode technique, which makes the design fully compatible with standard digital CMOS processes. The A/D converter, which is designed in TSMC 0.35 μm CMOS process, achieves 8 bits of resolution at a clock frequency of 100MHz. Simulated results show that the SFDR is better than 62 dB and the DNL and INL are 0.4 LSB. The A/D converter operates from a symmetrical +/-1.65 V supply. The power dissipated by the analog circuitry is 150mW.
