SUMMARY This paper describes a flash ADC using interpolation (IP) and cyclic background self-calibrating techniques. The proposed IP technique that is cascade of capacitor IP and gate IP with dynamic double-tail latched comparator reduces non-linearity, power consumption, and occupied area. The cyclic background self-calibrating technique periodically(More)
— This paper presents a 0.55 V, 7-bit, 160 MS/s pipeline ADC using dynamic amplifiers. In this ADC, dynamic amplifiers with a common-mode detection technique are used as residual amplifiers to increase its robustness against supply voltage lowering. These amplifiers also remove the unnecessary static power consumption achieving clock-scalability in power(More)
SUMMARY This paper analyzes a pseudo-differential dynamic com-parator with a dynamic pre-amplifier. The transient gain of a dynamic pre-amplifier is derived and applied to equations of the thermal noise and the regeneration time of a comparator. This analysis enhances understanding of the roles of transistor's parameters in pre-amplifier's gain. Based on(More)
