Title: Method and apparatus for clock frequency multiplier
Inventor: PETER J HOLZMANN
IPC: H03K5/135
Filed: 2017-09-05
Abstract: In a clock frequency multiplier, an input clock is supplied to a digital programmable delay circuit, and an inverted input clock is supplied to another digital programmable delay. An output of the digital programmable delay circuit is combined with the input clock and an inverted clock through AND gates in order to generate clock pulses at both a rising and a falling edge of a clock. An input clock signal and an inverted clock signal are combined through OR gates to provide an output clock signal with a frequency that doubles a frequency of the input clock. Values of control bits for the digital programmable delay circuit are determined in a time-to-digital conversion (TDC) circuit that includes a successive approximation register (SAR). For every cycle of the clock, an SAR circuit successively sets the programmable delay control bits and compares a delay circuit output with the input clock to determine the value of the control bits.
