Low-Voltage Multi-input High Trans-conductance Amplifier using Flipped Voltage Follower and its application in High Pass Filter

In this paper, a multi-input transconductance amplifier using Fully Differential Flipped Voltage Follower (FDFVF) has been proposed. The proposed circuit works at low supply voltage and produces large output current while using minimum number of active and passive elements. FVF technique has been used due to its differential characteristics along with low voltage and low power operation. Also proposed work realizes a high pass filter. The simulations of FDFVF based amplifier and its application in high pass filter has been shown using LTspice XVII.
