Abstract
In this paper, a new voltage-controlled tunable integrator for low-voltage applications is proposed. The proposed active element is composed of the CMOS complementary cascode circuit which can extend transconductance of an element. Therefore, the unity gain frequency which is determined transcon-ductance is increased than that of the conventional element. And then these results are verified by the $0.25{\mu}m$ CMOS n-well parameter HSPICE simulation. As a result, the gain and the unity gain frequency are 42dB and 200MHz respectively in the element on 2V supply voltage. And power dissipation of the designed circuit is 0.32mW.
