A new ultra-low-voltage (LV) low-power (LP) bulk-driven quasi-floating-gate (BD-QFG) operational transconductance amplifier (OTA) is presented in this paper. The proposed circuit is designed using 0.18 μm CMOS technology. A supply voltage of ±0.3 V and a quiescent bias current of 5 μA are used. The PSpice simulation result shows that the power consumption of the proposed BD-QFG OTA is 13.4 μW. Thus, the circuit is suitable for low-power applications. In order to confirm that the proposed BD-QFG OTA can be used in analog signal processing, a BD-QFG OTA-based diodeless precision rectifier is designed as an example application. This rectifier employs only two BD-QFG OTAs and consumes only 26.8 μW.
In this paper, an exuberant inductor (ai) with high linearity and high powerful range, together with a base scope of parts, is displayed. This paper offers a compelling method to perceive a cmos band skip channel of low power utilization by method for variety of transconductance in expressions of inclination front line change. The outlined sift through works in a sensibly high recurrence assortment. The reenactment and test results are accommodated 130 nm tsmc13rf rhythm virtuoso.
