In a typical transistor bias circuit, stability is achieved through the use of an emitter resistor and reliance on a stable supply voltage. However, the emitter resistor is undesirable. It helps maintain bias stability but has the undesirable effects of degrading noise figure and stability due to imperfect bypassing of the emitter.
