Amplifier Input/Output Impedence Modification TRIZ Cases
- Bootstrapped Unity Gain Follower With Buffered Feedback Stability
An added unity gain buffer bootstraps the input stage to cut capacitance and source-impedance errors without destabilizing the amplifier.
- RF Amplifier Gain Flattening Using Dissipative Transmission Lines
A resistive dissipative circuit with tuned open or shorted transmission lines flattens RF amplifier gain across frequency ranges.
- Output Matching Trap Circuit for Wideband Harmonic Suppression
Multiple series-resonant trap circuits keep output impedance near short at harmonic bands, suppressing second and third radiation efficiently.
- Transistor Circuit Impedance Transformation
Subthreshold gate-source voltages boost giga-ohm input impedance while minimizing silicon area consumption.
