Operational Amplifiers (OPAMP) The ideal OPAMP, open-loop gain, input resistance and output resistance. Characteristics of real Op-Amps: open-loop transfer function, voltage gain, bandwidth, slew rate, power bandwidth, clipping, offset voltages and currents, rejection ratios. OPAMP Applications Linear applications: (Inverting and Non- Inverting amplifiers, Differential and Summing amplifiers, Integrators and Differentiators), Nonlinear applications (precision rectifiers, peak detectors, Schmitt-trigger comparator and logarithmic amplifiers). Active Filters Low-pass, high-pass, band-pass and band-stop sections, Butterworth, Chebyshev, Elliptic and Bessel functions, circuit realization of single pole and two-pole transfer functions; frequency and impedance scaling. Implementation of filters using OPAMPs. Data conversion circuits Analog to Digital converters: definitions, codes, LSB, MSB, linearity, differential linearity, offset and gain errors, missing codes; Counting converters: successive approximations, single-and-dual slope converters, flash converters, delta-sigma converters; Sample-and-hold circuits, sampling rate selection and setting, integrating an analog signal to a digital system.Digital to Analog converters: definitions, codes, LSB, MSB, linearity, differential linearity, offset and gain errors; weighted resistor D/A converter; R/2R ladders and D/A converters; weighted current source converters; integrating a digital signal to an analog system. Clock synchronizing the Analog to Digital and Digital to Analog conversion operations using system clock signals. Oscillators Basic concepts and definitions; Wien-bridge oscillator Circuit modeling and simulation Introduction to electronic Computer Aided Design (CAD) tools, dc analysis, ac analysis, transient analysis; simulation control options, built-in-solid-state device models, device parameter control libraries, Designing electronic circuits. Logic Circuits SOP and POS representation for logic functions, K-map representation, simplification of logic functions using K-map, minimization of logical functions, don’t care conditions.
