General frequency considerations for single stage or multi stage network: low and high frequency analysis and bode plot, multistage frequency effect and determining the cut-off frequencies. Operational Amplifiers (Op-Amp): Op-amp characteristics, open loop voltage gain, differential input voltage, inverting amplifier, inverting adder, non-inverting amplifier, voltage follower, differentiator, integrator, subtractor, CMRR, zero crossing and voltage level detector, hysteresis and their applications. Signal generators using op-amp: square, triangle, sawtooth and sine wave. DC performance: bias, offset and drift. AC performance: frequency parameter, unity-gain bandwidth, slew rate and noise. Various applications of op-amps: Precision Rectifier, MAV circuit, peak detector, precision clipper, Differential, Instrumentation and bridge amplifier. Active filter: frequency response of low pass, High pass, Band pass and Band stop filters for ideal and practical conditions; Band pass filter: narrow-band and wide-band filter. Feedback Amplifier: classification of amplifier as voltage, current, trans-resistance and trans-conductance amplifier, effect of feedback on amplifier bandwidth, condition of stability and the Nyquest criterion. Sinusoidal oscillator: the Barkhausen criterion, phase shift oscillator, general form of oscillator circuits; Colpitts oscillator, Hartley Oscillator, Crystal oscillator. Power Supplies (Voltage regulator), pnpn devices: SCR, SCS, DIAC, TRIAC, UJT. Timer circuit design, Multivibrators: Astable, monostable and bistable multivibrators.
