Abstract

ABSTRACT: This paper reports a first-order voltage mode and trans-admittance mode universal filter from the same circuit structure. This configuration employs a single Differential Voltage Extra-X Current Controlled Current Conveyor (DV-EXCCCII) and one capacitor to realise a first-order Low Pass Filter (LPF), High Pass Filter (HPF), and All Pass Filter (APF) in voltage mode and trans-admittance mode. The DV-EXCCCII is an electronically tunable analog block, so the filter response can be varied with the bias current of the DV-EXCCCII. No matching constraints are necessary to realise the proposed filter. The sensitivity is found to be low because of passive components and also due to non-idealities. The reported circuit configuration is implemented through CADENCE VIRTUOSO and verified in SPECTRE using 0.18 µm UMC CMOS technology process parameters.
