Abstract

Describes a tunable differential voltage-controlled current source (DVCCS) realization scheme using operational amplifier (OA) devices. Studies on its design, realizability, and some high-frequency applications are included. Detailed analysis towards the investigation of the high-frequency nonidealities and their appropriate compensation schemes are proposed, employing the one-pole frequency-dependence of the OA devices. Applicabilities of the tunable DVCCS in the high-frequency high-Q tunable inverting/noninverting integrator (TII/TNI) network realization are reported. Significant improvement has been obtained in the integrator quality factors, Q, over the existing schemes, with no effect on tunability.
