Current Controlled Transconductance Amplifier (CCTA) using Advanced Design System

Complementary Metal Oxide Semiconductor (CMOS) is a technology used to produce integrated circuit. CMOS circuits are found in several types of electronic components, including microprocessors, batteries and digital camera image sensors. The MOS in CMOS refers to the transistor in a CMOS component called MOSFETs (metal oxide semiconductor field-effect transistors). In the project we are going to design novel CCCCTA, developed in CMOS technology using Advanced Design System (ADS). Current conveyors are unity gain active building block having high linearity, wide dynamic range and provide higher gain-bandwidth product. The current conveyors operate at low voltage supplies and consume less power. It has high input impedance, low output impedance, high CMRR and high slew rate. The current mode circuits such as Current conveyors have emerged as an important class of circuits in the field of analog electronics. The new structured CCCCTA the balanced differential-pair structure is used instead of the trans-linear structure as in the original CCCCTA and our proposed block are the requirements of bias current which is used to control the parasitic resistance at the input current port and the number of MOSFETs.
