Latest Patents

One of his latest patents is for a Multiple Stage Attenuator. This invention includes a first stage with a first operational amplifier and a tapped resistor. The tapped resistor has an input for receiving input data, an output coupled to the output of the first operational amplifier, and a plurality of taps for selectively presenting a sequence of voltages to the noninverting input of the first operational amplifier. Each of these sequences of voltages corresponds to an attenuation step, allowing the first stage to adjust the attenuation produced by the attenuator from an intermediate value to a predetermined ending value. The second stage includes a second operational amplifier and a tapped resistor, which receives analog data from the first stage and steps the attenuation from a predetermined starting value to the intermediate value.

Another significant patent involves circuits and methods for implementing audio codecs and systems using the same. This invention features audio data processing circuitry that includes a plurality of analog inputs for receiving analog audio data and a digital input for receiving digital audio data. An analog mixer is used to mix the analog data received at the plurality of analog inputs, generating a mixed analog audio stream. An analog-to-digital converter then converts this mixed analog audio stream to a digital audio stream, while a digital mixer combines digital data received at the digital input with the digital audio stream from the analog mixer to create a mixed digital audio stream.
