Abstract:
A tunable inter-stage matching circuit that can improve performance is described. In an exemplary design, an apparatus comprises a driver amplifier and a power amplifier. The apparatus may further include an inter-stage matching circuit tunable in discrete steps for matching impedances between the driver amplifier and the power amplifier. The tunable inter-stage matching circuit may include a bank of capacitors, each capacitor of the bank coupled in series with a switch for coupling the capacitor to a ground voltage.
