The recorded lectures are listed below.

1. Lecture#1(pdf): Introduction to PLLs
2. Lecture#2(pdf): Crystal/LC oscillator as clock source, Basic operation of a PLL
3. Lecture#3(pdf): Basic operation of a PLL with mixer, loop filter, and voltage controlled oscillator at block level
4. Lecture#4(pdf): Basic operation of a PLL with mixer, loop filter, and voltage controlled oscillator at block level (contd.)

Assignments will be posted below. You are expected to solve them on your own. You should submit each one by 09:00AM of the due date mentioned. Copying will carry strict penalties.

Topics include analog and digital integer-N phase-locked loops (PLLs). Building blocks include phase/frequency detectors, charge-pump, LC/ring-oscillators, multi-modulus frequency dividers, active/passive loop-filter, etc.

To develop intuition behind frequency synthesizer design, learning mathematical basis behind operation, and realizing PLLs at architecture and transistor level.
