Abstract :
A 10-bit 60-MS/s low-power CMOS pipelined analog-to-digital converter (ADC) is proposed. At the front-end, a timing-skew-insensitive double-sampled Miller-capacitance-based sample-and-hold circuit is employed to enhance the dynamic performance of the pipelined ADC. Bootstrapped switch achieves rail-to-rail signal swing at low-voltage power supply. Employing double sampling and bias current scaling techniques, very competitive power consumption can be achieved. The prototype chips have been fabricated and experimental results confirm the feasibility of this new technique.
