Operational transconductance amplifiers (OTAs) are considered to be promising as the building blocks for filters, oscillators at high frequencies. Recently, OTAs are developed in three trends- high frequency, high linearity and low power. OTA-C filters are one of the most widely used continuous time filters. In this work, high gain and wide bandwidth operational transconductance amplifier is designed. Further, second order low pass filter and high pass has also been realized using proposed OTA-II. The proposed filter shows wide pass bandwidth along with higher quality factor. The proposed…mehr

Operational transconductance amplifiers (OTAs) are considered to be promising as the building blocks for filters, oscillators at high frequencies. Recently, OTAs are developed in three trends- high frequency, high linearity and low power. OTA-C filters are one of the most widely used continuous time filters. In this work, high gain and wide bandwidth operational transconductance amplifier is designed. Further, second order low pass filter and high pass has also been realized using proposed OTA-II. The proposed filter shows wide pass bandwidth along with higher quality factor. The proposed filter also shows lower power dissipation as compare to existing circuit.
