Abstract :
The design of a tunable high-frequency fully integrated bipolar operational transconductance amplifier (OTA) is presented. Techniques resulting in tunability and broadbanding are discussed, as well as unavoidable trade-offs resulting from the lack of a vertical positive-negative-positive (PNP) device. Using an 8-GHz bipolar transistor array process, the OTA had a -3-dB frequency response of more than 2.7 GHz and a maximum linear input range of ±2.5 V, and it dissipated 28 mW for a power supply of ±5 V. Two applications of the OTA in OTA-C filter design are presented
