A 9hit, 1.8V, 165MSis pipelined ADC was built in a 0. 2 1 ~ CMOS digital process. The inter-stage amplifier in this converter was built using all digital transistors. To get sufficient gain with digital transistors a self-adjusting positive feedback operational amplifier that shows low sensitivity to output swing was used. The ADC consumed a total power of(More)
An integrated voltage-controlled oscillator using TSMC 0.18 mum CMOS technology is presented to demonstrate and compare the phase noise performance between the VCO using a new type of MEMS variable capacitor and that using conventional CMOS varactor, which is built on-chip together with the CMOS VCO. A representative MEMS variable capacitor, fabricated(More)
