Abstract: A periodic signal generator includes a resonant LC tank circuit that generates a periodic reference signal at a first frequency at a differential output thereof. A temperature-responsive frequency compensation module is electrically coupled to the differential output of the resonant LC tank circuit. This module includes a temperature dependent voltage control module that generates a temperature dependent control voltage and an array of switchable capacitive modules that is electrically coupled to a first node of the differential output of the resonant LC tank circuit and responsive to the temperature dependent control voltage and a plurality of switching coefficients. The array of switchable capacitive modules includes a fixed capacitor having a first terminal electrically coupled to the first node and a voltage-controlled variable capacitor having a first terminal electrically coupled to the first node.
