Week 04
Clippers and Clampers
I organize a study path from diodes to single-transistor amplifiers in the order that makes the circuit behavior easiest to revisit.
What I connect in this unit
A clipper limits waveform extrema at a diode conduction boundary, while a clamper stores charge to shift the DC level. A Zener regulator fixes an output near breakdown voltage, so each circuit requires piecewise operating regions.

Technical anchor
For a positive 0.7 V clipper, use Vout ≈ Vin when Vin ≤ 0.7 V and Vout ≈ 0.7 V when Vin > 0.7 V.
How I review it
Assume diode ON or OFF in each input interval, test whether the calculated voltages support that assumption, and mark the output DC level and clipping threshold.
