  • Patent number: 11387811
    Abstract: Some applications require a noise filter to have a very low cutoff frequency. The low cutoff frequency can require the use of a large resistor that is not suitable for integration in an integrated circuit (IC) package. Smaller components can be used to provide a large resistance in a first direction but not in another. In other words, the resistance of these smaller components may be non-reciprocal. A non-reciprocal resistance can affect a response of the noise filter to disruptions at the input or the output. Additionally, these smaller components may not be suitable for low voltage operation. A noise filter is disclosed that provides a high resistance using components that can be included in an integrated circuit package. The noise filter has a reciprocal effective resistance and can utilize technology suitable for low voltage operation.

  • Patent number: 11374565
    Abstract: This disclosure relates to apparatus and methods for radio-frequency (RF) switching circuits, and more particularly for a PIN diode driver circuit for high speed, high repetition rate and/or high power applications. The PIN diode driver may include a dual voltage reverse bias provided to the PIN diode, which dual voltage reverse bias may be provided by a first, relatively lower voltage, power supply and a second, relatively higher voltage, power supply. The relatively lower voltage is to discharge an intrinsic layer of the PIN diode at a lower voltage than during reverse bias of the PIN diode at the second relatively higher bias voltage in order to reduce overall power consumption.
