“…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.

“…In the literature, diverse techniques unconventional have been developed to construct the low supply voltage and the low consumption CMOS circuits. The important techniques are the floating-gate (FG) [2], the quasi-floating-gate (QFG) [3] and the bulk-driven (BD) [4]. These techniques have many advantages and disadvantages.…”

A regulated cascode current mirror (RGC) and its improved version with bulk driven quasi floating gate technique (BD-QFG) are presented in this paper. The proposed BD-QFG RGC current mirror (CM) is compared with the conventional (GD) RGC CM to show the performance improvement. The conventional and unconventional CM are implemented in Candace Virtuoso using 90 nm CMOS technology. For input current (Iin) varied from 0 to 200 μA and for 0.8 V supply voltage, the simulation results present that the proposed BD-QFG RGC CM has less variation in current transfer error (0.2%) as compared to the GD RGC CM (12%). The output voltage requirement for 200 µA input current is respectively 0.7 V and 0.17 V for the GD RGC CM and the BD-QFG RGC CM. The power consumption of the proposed circuit is 22.71 μW which is 0.15 μW higher than the GD RGC (22.56 μW). The total harmonic distortion (THD) of the proposed circuit is 0.4% which is 1.1% less than the conventional circuit (1.5%). All these improvements in the proposed BD-QFG RGC CM are attained at a cost of 0.05 GHz reduction in frequency (2.31 GHz). The minimum supply voltage of BD-QFG RGC CM and GD RGC CM is 0.4 V and

A high performance low voltage bulk driven quasi floating gate MOS based current mirror has been proposed. The combination of bulk driven and quasi FGMOS decreases the input impedance upto 120 Ω which is four times smaller than current mirror based on only bulk driven technique. The bandwidth has also been improved upto 173 MHz which is three folds of bandwidth of conventional bulk driven current mirror. Very high output impedance upto 1GΩ is achieved using self cascode technique in output section depending the value of factor m. Small signal analysis of proposed circuit verifies the simulated results. The circuit is simulated using 0.18μm CMOS technology with supply voltage of ±0.3V. The proposed current mirror is highly suitable for low voltage applications.
