A 1.2 V 16 MHz Phase Domain Analog–to–Digital Converter

A phase–domain approach of I/Q–quantization for
RF Transceivers is presented. The I/Q–signals are
converted directly from the phase domain into a
digital representation of the actual phasor position.
This phase–domain Analog–to–digital converter
(Phase–ADC) designed in 0.18μm occupies an area
of 0.049 mm2, has a dynamic range of 50 dB and
draws roughly 300 μA from 1.2 Volt
