  • Publication number: 20230221744
    Abstract: In certain aspects, a voltage regulator includes a pass transistor coupled between an input of the voltage regulator and an output of the voltage regulator, and an amplifier having a first input coupled to a reference voltage, a second input coupled to the output of the voltage regulator via a feedback path, and an output. The voltage regulator also includes a voltage booster coupled between the output of the amplifier and a gate of the pass transistor. In certain aspects, the voltage booster includes a first capacitor and a second capacitor for double charge pumping. In certain aspects, a control circuit of the voltage booster is coupled to a voltage source that is independent of an output voltage of the amplifier.

  • Patent number: 11043948
    Abstract: A bandwidth enhanced amplifier for high frequency CML To CMOS conversion is disclosed. In some implementations, an improved CML to CMOS converter includes a differential amplifier having a first and a second input transistors, and a first and a second load transistors. The first input transistor is coupled in series with the first load transistor, and the second input transistor is coupled in series with the second load transistor. The improved CML to CMOS converter further includes a first capacitor and a second capacitor. The first capacitor is coupled directly between a gate of the first input transistor and a gate of the first load transistor.

  • Patent number: 10965383
    Abstract: Certain aspects of the present disclosure generally relate to a sampling circuit, such as a sampling circuit for a low-voltage differential signaling (LVDS) serializer/deserializer (SerDes) system. One example sampling circuit generally includes a latching circuit and a plurality of pass-gate transistors. The latching circuit includes differential inputs, differential outputs, a clocked input circuit coupled to the differential inputs, a first cross-coupled circuit coupled to the clocked input circuit, and a second cross-coupled circuit coupled to the first cross-coupled circuit, wherein the first and second cross-coupled circuits are coupled to the differential outputs of the latching circuit. Each pass-gate transistor is coupled between one of the differential inputs of the latching circuit and a corresponding differential input of the sampling circuit.

  • Patent number: 10866627
    Abstract: A Universal Serial Bus (USB) Type-C connector subsystem is described herein. An integrated circuit (IC) chip device includes a Universal Serial Bus (USB) Type-C subsystem. The USB Type-C subsystem is to operate an Ra termination circuit that consumes no more than a first predetermined amount of current after the Ra termination circuit is applied to a Vconn line of the Type-C subsystem, or to operate a standby reference circuit in a low power mode of the device to perform detection on a Configuration Channel (CC) line of the Type-C subsystem, where the device consumes no more than a second predetermined amount of current in the low power mode.
