Abstract :
In this paper is presented an operational transconductance amplifier (OTA) core. With this core can be configured and reconfigured the two most frequently used OTA circuits - Miller´s OTA (with frequency correction) and simple OTA (without frequency correction). The core architecture is built of an analog transistor array, which allows examination of the circuits for a wide range of reference current. With these characteristics the described core is very appropriate for education in each contemporary course of analog VLSI electronics.
