Abstract :
The fully differential Opamp Reset Switching Technique (ORST) for low voltage applications is presented. The technique is demonstrated in a 1V, 10-bit, 60MS/s pipelined ADC where a hybrid ORST/Switched-RC topology is adopted for improved accuracy at low voltage supplies and achieves 50dB SNDR in 0.18µm CMOS while dissipating 34mW. The architecture also uses a passive input track-and-reset to save power and has an input bandwidth greater than 90MHz.
