IEICE TRANSACTIONS on Fundamentals
Low-Voltage, Wide-Common-Mode-Range and High-CMRR CMOS OTA
Summary :
In this paper, a low-voltage, wide-common-mode-range and high-CMRR OTA is presented. The proposed OTA consists of two circuit blocks; one is the input stage and operates as a differential level shifter, and the other is a highly linear output stage. Furthermore, the OTA can be operated in both weak and strong inversion regions. The proposed OTA is evaluated through Star-HSPICE with 0.18 µm CMOS device parameters (LEVEL53). Simulation results demonstrate a CMRR of 158 dB, a common-mode-input-range of 65 mV to 720 mV and a current consumption of 1.2 µA when VDD=0.8 V.
