Abstract
This paper presents two novel current-mode active-C phase equalizer circuits which are operated at low voltage. Both the proposed circuits employ single DXCCII as an active element, a NMOS transistor operated in the triode region as an active resistor and a capacitor. It is further been emphasized that the proposed structure of phase equalizers consists of active elements only along with a capacitor hence is named as active-C phase equalizers. Since the structure of the proposed circuits is based on active resistor, therefore both the proposed active-C phase equalizers can be easily tuned through gate voltage of active resistor. Moreover, the proposed phase equalizers enjoy the feature of high output impedance therefore it is easy to cascade the proposed circuits with other current-mode circuits. The proposed circuits also exhibit low active and passive sensitivities. Non-ideal analysis is further discussed. As an application, one of the proposed circuits is connected in cascade to get higher order active-C phase equalizer. The proposed circuits are verified through simulation results using PSPICE program on cadence tool.
