Noise Sources in Bulk CMOS

A nice summary on CMOS noise sources(flicker, shot, thermal).

Voltage Mode R-2R DAC: Theory of Operation

This document is about "how voltage mode R-2R DAC does work?". A major goal is to extract the math behind R-2R DAC intuitive structure.

Random DC Offset of Comparators

These slides review Flash ADC circuits. The source of random DC offset is the random fabrication mismatch. The reference paper, "Matching Properties of CMOS Transistors" (1989) divides the mismatch to two models: local and global.

Charge Injection in CMOS switches

"Charge Injection in Analog CMOS Switches" (1987) presents a model for charge injection. It also proposes some methods to alleviate charge injection by design.

Serial Charge Redistribution DAC

The slides introduce ABC of charge redistribution DAC.

Fractional Frequency Divider by Delta-Sigma Modulator

"Delta-sigma modulation in fractional-N frequency synthesis" (1993) compares pulse swallowing, phase interpolation, and Wheatley random jittering methods with Delta-Sigma jittering technique.

CMOS Capacitance and Delay

handy notes on CMOS delay. Analyse the capacitance and connect it to delay of circuits (driver load and total load capacitance).
