Advancement in VLSI technology has led to larger number of components on a single chip making it a reality to realize portable systems. Analog circuits are important in every VLSI systems such as filters, current and voltage amplifiers, comparators, A/D and D/A converters, etc. Miniaturization in circuit design requires Low-Power Low-Voltage (LPLV) analog integrated circuits to be designed. Analog signal processing's inherent advantage of low power and high speed has led to extensive research in analog domain.
