![]() Usually you’d keep the bases unconnected you’d connect top base to a reference voltage and feed the signal into the bottom base. Any other practical suggestions or design tips? Although, my biasing calculations for R1 and R2 are guess and check in the B2. Our professor suggested grounding surrounding pins. We are soldering our circuits to perf board. To measure frequency response on a scope, measure on the output of the cascode through a buffer. The capacitance from even a 1MHz scope probe will roll the frequency of this amplifier off at 2 MHz. So far, no one in the course has gotten both primary spec: I have four questions about the cascode BJT amplifier.

The cascode amplifier is the two stage amplifier in which common emitter stage is connected to common base stage.
