The 555 timer is a simple integrated circuit that can be used to make many different electronic circuits
such as a pulse source, tone source, one-shot and a light flasher.
1. Performed a DC and AC analysis of the two-stage class A amplifier shown in Figure 1.
2. Constricted the circuit and measures and recorded the DC voltages and current values at the
critical points of each stage.
Applied a 1 Vp-p 1
The JFET is always operated with the gate-source pn junction reverse-biased. Reversebiasing of the gatesource junction with a negative gate voltage produces a depletion region along the pn junction, which
extends into the n channel and thus increases its
