Negative impedance converter circuits (NICs) are important building blocks in design and manufacturing of analog and mixed mode integrated circuits. In this paper, a catalogue of single current feedback amplifier-based negative impedance converter circuits having impedance scaling properties is proposed. Various examples are presented to illustrate the versatility of proposed NIC circuits.

The presented tool “Plantage+” significantly speeds up the layout process of analog circuits. Integrated in an industrial IC design environment, the tool recognizes basic building blocks in the circuit. It automatically sets up constraints and generates layouts using a deterministic algorithm.

The operational amplifiers (OPAMP) are basic building blocks in implementing a variety of analog circuits such as amplifiers, filters, integrators, differentiators, summers, oscillators etc. OPAMPs work well for lowfrequency applications, such as audio and video systems. For higher frequencies, however, OPAMP designs become difficult due to their frequency limit. At those high frequencies, oper...

Versatile dual-mode class-AB CMOS four-quadrant analog multiplier circuit is presented. The dual translinear loops and current mirrors are the basic building blocks in realization scheme. This technique provides; wide dynamic range, wide-bandwidth response and low power consumption. The major advantages of this approach are; its has single ended inputs; since its input is dual translinear loop ...

An area receiving significant attention both from academia and industry is data communications. Great effort is being placed at pushing data transmission rates over copper to near the Shannon limit which requires support electronics such as filters operating in the VHF range. Thus, tuning mechanisms are essential to accommodate fabrication and channel variations. One technology to accommodate t...
