  • Zero phase circuit for sampled data phase locked loop
    Patent number: 5805001
    Abstract: A circuit provides a restart signal to indicate a zero crossing of a continuous varying signal. A zero phase signal is generalized based on a zero crossing of the continuous varying signal. The continuous varying signal is sampled and held in accordance with the zero crossing. The continuous varying signal is converted to complementary signals, and these complementary signals are in turn converted to a signal appropriate for CMOS circuits.
