COURSE OBJECTIVE

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

 

COURSE CONTENT

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,  f 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.
