Abstract :
We present the design of a 7-bit 200 MS/s pipelined ADC with switched open-loop amplifiers in a 65 nm CMOS technology. As a result of turning off the open-loop amplifiers during sampling we reduce the power dissipation by 23%. The ADC achieves a SNDR of 40 dB close to the Nyquist frequency, with a power dissipation of 2 mW, which results in a Walden FOM of 0.13 pJ/step and a Thermal FOM of 1.6 fJ/step.
