Latest Patents

One of his latest patents is focused on a low power free running oscillator. This invention includes a switch capacitor based frequency-to-voltage converter (F2V), a comparator, and a voltage controlled oscillator (VCO). The design aims to reduce amplifier offset and flicker noise while enhancing the effective gain of the comparator's amplifier. The F2V generates a feedback voltage corresponding to the frequencies output by the VCO. The comparator samples a reference voltage and compares it to the feedback voltage, generating an output based on their difference. This output is integrated using an integrating capacitor, with the design compensating for parasitic capacitance through a dual-output amplifier configuration.

Another patent by Keekstra also pertains to a low power free running oscillator. This invention features a voltage controlled oscillator circuit that receives an input voltage to control the frequency of its oscillation signal. It includes a frequency-to-voltage circuit that produces a voltage dependent on the oscillation signal's frequency. The comparison circuit consists of two amplifiers that work together to process the voltage differences, utilizing sampling and integration capacitors to enhance performance.
