Latest Patents

Muir holds a patent for a "Delta-sigma modulator approach to increased amplifier gain resolution." This invention involves a variable gain amplifier device that enhances gain resolution. The device comprises a programmable gain amplifier (PGA), an analog-to-digital converter (ADC), an automatic level control (ALC) algorithm, and a delta-sigma modulator. The PGA is designed to receive and amplify an analog input signal, generating an analog output signal. The ADC converts this analog output signal into a digital signal, while the ALC algorithm processes the digital signal to produce a control code. The delta-sigma modulator then generates a pulse-density modulated (PDM) signal, which is fed back to the PGA to control the switchable resistor network.
