Summary:
In this paper, we propose a low-power OTA for CMOS cellular neural networks (CNN) cell. The OTA use MOSFETs operating in the weak inversion region. The transconductance can be changed by changing the external bias voltage. From the results of HSPICE simulation, the power consumption of the proposed OTA is less than 3.5 micro-watts with 1.2 V power supply. As an application of the proposed OTA, an oscillatory CNN circuit using two CNN cells with the proposed OTA is presented.
