  • Click-pop noise suppression system
    Patent number: 8526636
    Abstract: A click-noise suppression system having MOSFET transistor switches positioned between the preamplifiers and coupling capacitors of an audio system wherein the suppression system maintains the switches off when the system is turned on until a charging circuit increases the gate voltage of the switches. The switches quickly turn off and the coupling capacitors are discharged through discharge resistors when the system is turned off.

  • DIGITAL CONTROL SYSTEM AND METHOD
    Publication number: 20100019820
    Abstract: A low power monolithic CMOS device incorporating functions to control power supply transition noise such as in audio circuits and systems. The digital control circuit incorporates MOSFETs that are maintained in an OFF state during normal operation and are turned ON only when system power is turned on or off to thus eliminate the need for bias voltages and maintain minimal quiescent current.
