Latest Patents

Venkataraman holds a patent titled "Methods for determining optimum power supply voltages for radio-frequency power amplifier circuitry." This patent focuses on electronic devices with wireless communications capabilities. The invention includes storage and processing circuitry, power amplifier circuitry, and power supply circuitry. The storage and processing circuitry directs the power amplifier to operate in a desired gain mode, on a specific radio channel, and at a given output power level. The power supply circuitry biases the power amplifier with a power supply voltage. The performance of the power amplifier is characterized by an adjacent channel leakage ratio (ACLR) margin, while its power consumption is characterized by a current savings ratio. A cost function is calculated by taking the product of the ACLR margin and current savings ratio, allowing for the determination of a minimum point for each cost function curve. This innovation aims to optimize the biasing of the power amplifier circuitry with a supply voltage corresponding to the minimum point.
