Oscillator based on thermal diffusion

KAA Makinwa (Inventor), JF Witte (Inventor)

Research output: Patent


An oscillator device for generating an oscillator signal, includes a heater arrangement, a first switching element, a temperature sensor, signal process means, and voltage controlled oscillator; an output of the temperature sensor being connected to an input of the signal processing means, and an output of the signal processing means being connected to an input of the voltage controlled oscillator. The first switching element is arranged for receiving the oscillator signal from the voltage controlled oscillator and for providing a heater drive signal to either a first heater element or a second heater element of the heater arrangement based on the oscillator signal. The signal processing means comprise a synchronous demodulator.
