Latest Patents
One of his latest patents is focused on harmonic filtering for high power radio frequency (RF) communications. This patent discloses systems and methods for on-chip harmonic filtering, which includes a filter circuit that is coupled between a first internal node and a connection pad for an integrated circuit. The filter circuit comprises a first inductance, a variable capacitance, and a second inductance. The capacitance amount for the variable capacitance is controlled to tune filtering for the filter circuit to a harmonic of a frequency for a transmit output signal. A power amplifier outputs the transmit output signal to the connection pad without passing through the filter circuit, while the filter circuit effectively filters the harmonic of the frequency for the transmit output signal, shunting harmonic current to ground. In one embodiment, the filtered harmonic is a third harmonic of the transmit frequency, and the transmit output signal has an output power greater than or equal to 15 dBm.
Another notable patent is a differential circuit calibration apparatus and method. This apparatus is designed for calibrating a differential circuit that includes a differential integrator with an input, a gain, and an output connected to a comparator. The differential integrator output is chargeable to a threshold prior to an integration period. During the integration period, the differential integrator integrates the input, causing the output to approach zero from the threshold. The comparator detects when the output of the differential integrator reaches zero. The apparatus features a closed-loop gain trim circuit for coarse calibration to adjust and set the gain of the differential integrator, along with a reference generator that produces the threshold for pre-charging the differential integrator output. This reference generator is trimmable during fine calibration to correct for any residual gain error in the differential circuit.
