This unit consists of two interrelated parts that will be taught in copncurrently:

Part I - Circuit Theory

Conceptual models based on voltage and current, lumped models for components; passive elements—capacitor, single inductor, coupled inductors, resistor; active elements—controlled and uncontrolled; Kirchhoff’s laws, superposition, ordinary differential equations, state space, duality; time domain analysis—initial conditions, transient response, forced response, first and second order circuits with R, L, C elements; Laplace transform in the analysis of circuits, s domain characteristics of lumped elements, application of Kirchhoff’s laws in s domain; systematic analysis—Nodal and Mesh, definite and indefinite matrix representation. Thevenin, Norton equivalents; properties of impedance functions, L C networks, R L C networks; frequency and impedance scaling; instantaneous power, complex power, Tellegen’s theorem, maximum power transfer; two-port networks: voltage-current relations for two ports; matrix description of two ports, examples and applications, relationships between two-port matrices; properties of two-port functions for active and passive networks, pole and zero locations; cascaded two-port networks, constant resistance networks.

Part II - Electronic Circuits

Transistors as digital switches, basic DC characteristics and applications; linear transistor amplifiers—basic single stage configurations, biasing, limits of operation; small signal modelling and analysis of single stage configurations, impedance and transfer frequency characteristics, Miller effect; signal referencing, input and output references; two-stage configurations, voltage to current, current to voltage pairs, cascode stage, differential amplifier stage, differential gain, common mode gain.
