Abstract:
1. A system for providing a programmable clock phase, comprising: a phase separation module configured and disposed to receive a first input signal and a second input signal and generate an integrative signal; a reference DAC supply module configured and disposed to receive the integrative signal from the phase separation module and output a DAC reference voltage; and a phase creator module, comprising a DAC and an output signal generation circuit, and wherein the phase creator module is configured and disposed to use the DAC reference voltage as an input to the DAC, and wherein the DAC is configured and disposed to output a DAC output voltage signal, and wherein the DAC output voltage signal is configured to control the output signal generation circuit and wherein the reference DAC supply module comprises: a sample-and-hold circuit configured and disposed to receive the integrative signal; a reference DAC edge pulse generator configured to activate the sample-and-hold circuit, wherein the reference DAC edge pulse generator is configured and disposed to receive the second input signal.
