Patent Number Title Of Patent Date Issued
8564327 USB isolator with advanced control features October 22, 2013
A USB-based isolator system conveys USB signals between a pair of galvanically isolated circuit systems and supports controlled enumeration by a downstream device on upstream USB signal lines. The isolator system provides a multi-mode voltage regulator to support multiple voltage sup
7872522 Noise reduction system and method for audio switching amplifier January 18, 2011
Noise reduction for a switching amplifier system having a differential output stage and demodulator filter responsive to complementary PWM signals includes generating in-phase PWM signals and gradually adjusting their duty cycle between a low duty cycle and the full duty cycle of the
7053807 Apparatus and method for controlling the state variable of an integrator stage in a modulator May 30, 2006
An apparatus for controlling the state variable of an integrator stage in a modulator including a detector circuit for generating an overload signal when the modulator is overdriven, a control circuit responsive to the overload signal for generating switching control signals during the
6924757 Sigma-delta modulator with reduced switching rate for use in class-D amplification August 2, 2005
A sigma delta modulator includes a modulator module that includes a quantizer with variable hysteresis, which receives an input signal to perform necessary modulation operations. A non-linear mapping module receives a signal associated with said input signal and tabulates the necessa
