ABSTRACT
An ideal operational transconductance amplifier (OTA) is a voltage-controlled current source. What is important and useful about the OTA’s transconductance parameter is that it is controlled by an external current, the amplifier current Ib , so that one obtains () g m = 20 V i I B https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315219349/0b4b3a4c-2959-4ab2-9b4b-af7cc5bdb41c/content/eq1016.tif"/>
