Abstract
A transistor-based filter for inhibiting load noise from entering a power supply is disclosed. The filter includes a first transistor having an emitter coupled to a power supply, a collector coupled to a load, and a base. The filter also includes a first capacitor coupled between the base of the first transistor and a ground terminal. The filter further includes an impedance coupled between the base and a node between the collector and the load, or a second transistor and second capacitor. The impedance can be a resistor or an inductor.

A transistor-based filter for inhibiting load noise from entering a power supply, comprising:
- a. a first transistor with an emitter coupled to a power supply, a collector directly coupled to a load, and a base;
- b. a first capacitor coupled between the base and a ground terminal;
- and
- c. a first impedance coupled between the base and a node between the collector and the load.
