Latest Patents
Harold A Witlinger holds a patent for a Class D modulator with peak current limit and load impedance sensing circuits. This invention addresses overcurrent conditions in both upper and lower FETs. The modulator receives two logic signals to manage these conditions effectively. When an overcurrent condition occurs in the upper FET, a PMOS transistor activates to inject current into the summing junction of the integrator. This action turns off the upper FET and turns on the lower FET, resulting in gain compression of the audio signal. Conversely, when the overcurrent condition is in the lower FET, an NMOS transistor pulls current out of the summing junction, turning off the lower FET and turning on the upper FET. This dynamic adjustment reduces the current in the lower FET, thereby affecting the gain at audio frequencies.
