It is to be mentioned that in absence of added resistance RD2
or on the simultaneous removal of RD1 and RD2 from the
proposed circuit, the output voltage/current waveforms of the
amplifier distorted badly while on removing only RD1 from the
proposed circuit, the positive half cycle of the output
waveform clipped off. Similarly, another interesting feature of
proposed amplifier is obtained when the biasing resistance R1
is removed from the circuit. This yields enhancement in
maximum voltage gain to 188.97 value, peak output current to
168.30 μA, peak output voltage to 1.683 volts but reduction in
maximum current gain to a 4.9398 value and bandwidth to
1.073MHz. On the other hand, if R2 is made absent from the
proposed circuit, the output voltage/current waveforms again
distorted badly.
