Design of Topologies of Current Controlled Current Conveyor in 16 nm Bulk CMOS Technology

Advancement in VLSI technology has led to larger number of components on a single chip making it a reality to realise 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 lowpower 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. Current domain processing having advantages of higher bandwidth, large dynamic range, greater linearity, simple circuitry seems to be the solution. Among the number of current mode topologies current conveyor is the most versatile building block. The second generation Current controlled current conveyor (CCCII) has attained greater popularity in recent years due to electronic adjustability of its X-terminal intrinsic resistance through bias current. Here we have designed three topologies of CCCII found in literature namely dual output current controlled current conveyor (DOCCCII), current controlled current conveyor transconductance amplifier (CCCCTA) and digitally programmable current controlled current conveyor (DPCCCII) in 16nm bulk CMOS technology using PTM (High Performance 16nm Metal Gate / High-K / Strained-Si parameter).
