EL517

EL517 - Advanced analog design
The course mainly comprises of the following topics :
Feedback: ideal feedback equation; properties of feedback (gain insensitivity, effect on distortion); feedback configurations: series-shunt, shunt-shunt, shunt-series, series-series; effect of loading; practical examples; voltage regulator. Noise in integrated circuits:sources of noise (shot, thermal & flicker noise); noise models for diodes, BJT and MOSFET; noise in MOSFET and BJT circuits; uncorrelated and correlated noise sources; minimum detectable signal(MDS); equivalent input noise generators in BJT and MOSFET; effect of feedback on noise performance; noise in differential pairs; noise bandwidth; noise figure; Operational Amplifiers: small and large signal bandwidth; settling time; single-stage opamps, cascoded load; folded-cascode opamp; two-stage opamp; gain-boosting; “trickle” bias; Stability of feedback amplifiers: theory of compensation; compensation in single-stage opamps; Miller compensation; root-locus techniques; Bandgap circuits: PTAT and bandgap principle; Switched-capacitor circuits: charge-injection, clock-feedthrough; switched-capacitor filters; successive-approximation A/D using charge-redistribution DAC; speed estimate; Oscillators: LC oscillators; negative resistance; ring VCO; jitter; phase noise; crystal oscillators; Phase-locked loops: modeling of PLL loop; stability analysis; basic measures of jitter; Gilbert Multipliers and mixers.
