    CMOS differential difference voltage follower transconductance amplifier
    (2016-01-27)
    Kumngern, Montree
    This paper presents a new active building block for analog circuit applications called differential difference voltage follower transconductance amplifier. It consists of two parts: first part is the input that provides a differential difference voltage follower and second part is the transconductance amplifier that uses to convert differential difference input voltage to the output current. Hence, the electronic tuning capability of the proposed active building block can be obtained. The active building block is used to realize a universal biquadratic filter as an example application. Simulation results using 0.5 μm standard CMOS process are used to confirm the proposed active building block.

    This paper presents a new current-mode precision rectifier using CMOS technology. The system comprises a current comparator, current mirrors and diodes that can realize either a half-wave rectifier or a full-wave rectifier into a single system by appropriately adjusting the current gain of a current mirror. The proposed circuit offers low-voltage supply, low-power dissipation and wide bandwidth. The simulation results can be confirmed the operation and performance of the proposed rectifier. © 2011 IEEE.
