RF Circuits

Pre-Requisite : EC206 and EC309
Contact Hours and Credits : ( 3 -0- 0 ) 3

Objective : 

To impart knowledge on basics of  IC design at RF frequencies.

Topics Covered :

Characteristics of passive IC components at RF frequencies – interconnects, resistors, capacitors, inductors and transformers – Transmission lines. Noise – classical two-port noise theory, noise models for active and passive components 

High frequency amplifier design – zeros as bandwidth enhancers, shunt-series amplifier, fT doublers, neutralization and unilateralization

Low noise amplifier design – LNA topologies, power constrained noise optimization, linearity and large signal performance

Mixers – multiplier-based mixers, subsampling mixers, diode-ring mixers

RF power amplifiers – Class A, AB, B, C, D, E and F amplifiers, modulation of power amplifiers, linearity considerations

Oscillators & synthesizers – describing functions, resonators, negative resistance oscillators, synthesis with static moduli, synthesis with dithering moduli, combination synthesizers – phase noise considerations.
