Abstract :
A 1.2V 6mW 500MS/s 5-bit ADC for use in a UWB receiver has been fabricated in a pure digital 65nm CMOS technology. The ADC uses a 6-channel time-interleaved successive approximation register architecture. Each of the channels has a split capacitor array to reduce switching energy and sensitivity to digital timing skew. A variable delay line is used to optimize the instant of latch strobing to reduce preamplifier currents
