  • Digital non-linearity compensation in a silicon microphone
    Patent number: 12170874
    Abstract: According to an embodiment, a digital microphone includes an analog-to-digital converter (ADC) for receiving an analog input signal; a DC blocker component coupled to the ADC; a digital low pass filter coupled to the DC block component; and a nonlinear compensation component coupled to the digital low pass filter for providing a digital output signal.

  • Startup Calibration and Digital Temperature Compensation for an Open-Loop VCO Based ADC Architecture
    Publication number: 20240396563
    Abstract: A digital microphone includes a first modulation path having an input for receiving an analog input signal and an output for generating a first digital signal; a second modulation path having an input for receiving the analog input signal and an output for generating a second digital signal; a summing circuit having a first input for receiving the first digital signal, a second input for receiving the second digital signal, and an output for generating a digital calibration path signal; and a difference circuit having a first input for receiving the first digital signal, a second input for receiving the second digital signal, and an output for generating a digital signal path signal.

  • EFFICIENT FILTERING ARCHITECTURE WITH REDUCED GROUP DELAY FOR DECOMPRESSION USING PREDICTOR
    Publication number: 20240322833
    Abstract: A digital microphone includes a log amplifier having an input for receiving an analog signal; an analog-to-digital converter (ADC) coupled to the log amplifier; a digital low-pass filter coupled to the ADC; a digital decompression component coupled to the digital low-pass filter; and a predictor filter coupled to the digital decompression component, the predictor filter having an output for generating a digital signal. The digital low-pass filter is a positive group delay filter and the predictor filter is a negative group delay filter. The digital microphone has an improved Signal-to-Noise Ratio (SNR) due to filtering, but without increasing overall group delay.
