ABSTRACT:
A phase detector operating in a low voltage environment and providing a substantially constant integral voltage over variations in temperature, supply voltage and process parameters. The quadrature phase detector includes an equalizer, a switching unit, a sampler and comparator unit and a bias generator. The bias generator includes a switched capacitor structure which produces a bias current which tracks fluctuations in capacitance values due to temperature, supply voltage and process variations. The errors introduced due to fluctuations in bias current and capacitance are thus minimized.
