Quasi Rail-to-Rail Very Low-Voltage OPAMP With a Single pMOS Input Differential Pair Academic Article

abstract

• In this brief, a quasi-rail-to-rail low-voltage operational amplifier (VDD-VSS-VDSATP-VDSATN) is introduced. A common-mode adapter that uses the common-mode voltage present at the common-source node of the available differential pair to accommodate the large common-mode input signal is proposed. The common-mode adapter operates properly at 300 kHz while driving a load capacitor of 15 pF and employs only 95 W of static power. The amplifier was fabricated in a standard AMI 0.5- m CMOS process ( Vtn= 0.7 V and Vtp= -0.9 V) and achieves an IM3 of 48 dB at 300 kHz for a two-tone input signal of 0.8 Vpk-pkA 1-V total supply voltage was used. 2006, IEEE.
