A tuning circuit (28) for compensating an inter-stage matching network (38) included in an integrated multistage radio frequency (RF) amplifier (22) includes one or more capacitors (30,32) connected in shunt between ground and a voltage supply to the amplifier (22). The capacitors (30,32) have values selected to effectively compensate the inductance from a pull-up inductor (42) included in the inter-stage matching network (38) to provide improved inter-stage matching when inductance and capacitance values of the inter-stage matching network deviate from their desired values due to parasitics and/or when other components, such as input-stage and output-stage transistors of the amplifiers deviate from their pre-fabrication simulation models. |
