Abstrakt

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
