Latest Patents

Wouter Groothedde holds a patent for a two-wire interface for digital microphones. This invention includes a power line and a ground line, utilizing the ground line as a 'voltage active line' to transmit both clock and data signals between the digital microphone circuit and a receiving circuit. The digital microphone circuit detects the clock signal on the voltage active line and uses it to operate an ADC, providing digital data. This digital data is then used to selectively drive current back to the receiving circuit over the voltage active line. The receiving circuit detects the transmitted data by monitoring the voltage associated with a line termination, with the impedance switched by the receiver circuit to modulate the clock signal.
