Learning Outcomes 1. Design a direct coupled amplifier and a typical operational ampli-
fier considering its Q-point stability and limitation of practical Am-
plifiers.
2. Design a typical tuned amplifier considering steps needed to en-
sure stability and alignability.

3. Design a typical oscillator to specifications by referring to the fac-
tors influencing the performance of sinusoidal and non-sinusoidal
oscillator circuits.
4. Design typical power supplies with specific out put voltage con-
sidering line and load variations and build in protection
Synopsis Direct coupled amplifier, the reasons for such system in IC technolo-
gy, advantage and disadvantages, suggested solution to the problem
of direct coupling. Cascode, NPN/PNP and cascade circuits. Ideal
operational Amplifier, Practical operational amplifier designs consid-
ering limitations. Op Amp Design project (with a formal report). Tuned
amplifiers, selectivity, single stage, multistage, stability, alignability

and frequency response. Theory of Oscillations, various classes of
oscillators, stability, amplitude limitation and non sinusoidal oscilla-
tors. Power supply design using zener diode and transistor. Line and
load regulations. Series and shunt regulators, feedback and fold-back
regulator. use of op amp in regulated power supplies. Voltage regu-
lated IC design
