An integrator circuit using voltage difference transconductance amplifier

Abstract This paper illustrates a novel design of voltage-mode Integrator using the active element, namely Voltage Difference Transconductance Amplifier (VDTA). The proposed circuit avails one VDTA element and a single capacitor. This provides more beneficial for the fabrication of ICs in VLSI design. The designed circuit works with ±0.9 V supply voltage, uses a bias current of order 150 µA and also its amplitude is electronically tunable with the bias current. The proposed circuit is designed in a gpdk 180 nm CMOS process using a Cadence Virtuoso tool and also has the power dissipation of order 270 µW. The simulation results are verified experimentally with the commercially available ICs LM13700.
