Latest Patents

Among his latest patents is the "Adaptive Low Power Common Mode Buffer." This invention includes a circuit with an amplifier that has first and second inputs and an output. A feedback circuit generates a feedback voltage in response to the output voltage of the amplifier. The feedback circuit is connected to the first input of the amplifier, providing the necessary feedback voltage. Additionally, an output circuit generates a variable bias current based on the amplifier's output voltage. A switch circuit allows the second input of the amplifier to alternate between a first reference voltage during one mode of operation and a second reference voltage during another mode.

Another significant patent is also titled "Adaptive Low Power Common Mode Buffer," which describes an analog to digital converter (ADC). This ADC features a conversion circuit that digitizes an input analog signal to produce an output digital signal. A current generator is responsible for generating a constant bias current. The current mirror circuit includes an input transistor that receives the constant bias current and an output transistor that mirrors this current to generate a variable bias current. A parallel transistor circuit selectively couples a parallel transistor in response to a control signal, which reflects the conversion rate of the ADC. A buffer is used to generate a common mode voltage for the conversion circuit from the variable bias current.
