“…Several CMOS circuits as analog switches, mixers, programmable-gain amplifiers, track and hold circuits, and digital-to-analog converters have been designed and realized using QFG transistors. All these circuits have been experimentally verified, confirming the usefulness and functionality of the proposed technique for very low-voltage applications [9]. Using proposed DVCC, a novel fully differential SC integrator is also introduced.…”

Abstract:This paper proposes a high performance, rail-to-rail, Differential Voltage Current Conveyor (DVCC), using Quasi-Floating Gate (QFG) transistors. With a compact structure, the circuit operates at very low supply voltage (±0.5 V), dissipates very low standby power (90 μW), has a high bandwidth (f −3 dB of 81 MHz and 82 MHz for Ai and Av, respectively), and a very low input resistance (0.2 Ω). Using the proposed DVCC a novel fully differential Switched Capacitor (SC) integrator is also introduced. HSPICE simulation results confirm the functionality of proposed DVCC and integrator.

“…Efficient implementation of large-valued resistors with one of their terminals connected to a power rail using reverse-biased PN junctions has been reported (for example in the quasi-floating gate technique presented in [2]). Floating PN junctions available within a transistor's well have been also proposed for this purpose [3].…”

Abstract:The implementation of large-valued floating resistive elements using MOS transistors in subthreshold region is addressed. The application of these elements to bias wideband AC coupled amplifiers is discussed. Simple schemes to generate the gate control voltages for the MOS transistors implementing large resistors so that they remain in high resistive state with large signal variations are discussed. Experimental results of a test chip prototype in 0.5-µm CMOS technology are presented that verify the proposed technique.

“…Floating Gate (FG) and Quasi-Floating Gate (QFG) FGMOS and QFGMOS [4] based circuits can operate at much lower supply. The advantage of these approaches lies in terms of linearity as the input coupling capacitor divider makes input signal to attenuate and increases the linearity.…”

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.
