Abstract:
1. A frequency generator comprising: a phase detector having first and second inputs and a first output; a loop filter coupled to the output of the phase detector; a voltage controlled oscillator coupled to the loop filter, the voltage controlled oscillator receiving a first voltage on a VCO input and generating a first signal on a VCO output having a frequency that is dependent on the first voltage, and wherein the VCO output is coupled to the first input of the phase detector; a transmission line having an input coupled to the VCO output for receiving the first signal and an output coupled to the second input of the phase detector, the transmission line providing a time delayed version of the first signal to the second input of the phase detector, wherein the phase detector, the loop filter, the voltage controlled oscillator and the transmission line are integrated on a single integrated circuit.
