Abstract Using a complementary bipolar junction transistor process having NPN transistors with a maximum short circuit common emitter gain-bandwidth product (ft) of 7.2 GHz and PNP transistors with a maximumft of 4.5 GHz, an operational transconductance amplifier has been designed for a 3-dB bandwidth of 7.2 GHz. The design process invokes new phase compensation strategies and develops innovative new ways of exploiting existing broadbanding techniques. The utility of the design is confirmed by demonstrating its application in two operational transconductance amplifier-capacitance filters. One of these examples is a 225 MHz lowpass filter, while the other is a bandpass filter with a center frequency of 250 MHz.
