“…Taking advantage of capacitor divider property, some QFG based transistors were used for design of very linear programmable CMOS OTA [9] which further used to implement tunable MOS resistors [10] and also GM-C filter [11]. Other recent published articles are based on current conveyor [12], CM having low input compliance voltage [13]. The experimental verification of QFG based circuits in literature proved to be a better technique for realizing low voltage power circuits.…”

Abstract-This paper presents a detail on various techniques to realize low voltage low power circuit. The techniques discussed are conventional gate-driven (GD), floating gate (FG), quasi-floating gate (QFG), bulk-driven (BD), and BD-QFG. The comparative analysis results in best performance achieved by BD-QFG approach. As BD circuits are well known approach for low power design, the combined effect QFG in bulk driven circuit results in enhanced performance. The complete analysis has been carried out in industry specific node UMC 0.18 micron technology with the help of HSpice simulator.

“…Recently, some papers proposed low supply-voltage (±0.5 V) CCIIs, and their theories were simulated in HSPICE but was not fabricated and validated into an integrated circuit [6]. In [5], the current conveyor is designed with rail-torail differential amplifiers and its second stage is a class AB cascoded current mirrors.…”

“…It is not suitable for low-voltage applications. In [6], the rail-to-rail second generation current conveyor based on quasi-floating gate transistors is presented. This circuit is using linear capacitors to couple the input signal to the gate terminal of the MOSFET transistor and its gate voltage is directly biased by a dc voltage through a diode-connection MOSFET transistor.…”

A low-voltage second-generation current conveyor (CCII) and its oscillator application suitable for portable systems are proposed in the paper. The proposed current conveyor is based on an inverter-based low-voltage error amplifier and a current mirror. There are no on-chip capacitors in the proposed current conveyor, and it can be designed with standard CMOS digital processes and hence will reduce the cost of chip fabrication. Moreover, the architecture of the proposed circuit without cascoded MOSFET transistors is easily designed and suitable for low-voltage operation. The CCII could be operated in a very low supply voltage such as ±0.5 V. The proposed CCII has been fabricated with TSMC 0.18 μm CMOS process and applied to low-voltage CCII oscillator suitable for portable systems.
