REVIEW PAPER ON PSEUDO-DIFFERENTIAL AND BULK-DRIVEN MOS TRANSISTOR TECHNIQUE FOR OTA

This paper presents review on Pseudo-Differential amplifier technique and Bulk-Driven MOS transistor technique for ultra-low voltage and power. By using this technique, a different design of operational transconductance amplifier (OTA) is briefly explained along with their outputs and their application. By using a pseudo-differential technique a voltage drop across the tail current is avoid as the tail-current is removed in Pseudo-differential amplifier where as by using the Bulk-Driven MOS transistor a minimum supply voltage is achieved because of the possibility in reduction of threshold voltage
