Abstract

A low-power, low-voltage CMOS fully differential operational transconductance amplifier (OTA) operating in weak inversion region is presented in this paper. The proposed element allows the use of very small current for low-power and low-voltage features. The performances are examined through PSPICE simulations, displaying usabilities of the new active element. The power consumption is about 221 nW at ±0.75 V and bias current I_E is 50 nA. The description includes example as a balance output full-wave rectifier.
