Abstract
This work presents a new active block called the differential current conveyor cascaded transconductance amplifier (DCCCTA) and implemented multi-mode biquadratic universal shadow filter. The frequency-hopping filter is implemented using a multi-mode universal shadow filter. The proposed circuit has two modes of operation: current mode (CM) and transadmittance mode (TAM). All-pass (AP), band-pass (BP), band-reject (BR), high-pass (HP), and low-pass (LP) responses are simultaneously accomplished. As intended, low input impedance for CM and high input impedance for TAM are acquired, while high output impedance is attained for both modes of operation. Inter-modulation distortion (IMD), percentage total harmonic distortion (%THD), and Monte Carlo analysis are also obtained. The theoretical results are verified using Cadence Virtuoso in 180 nm TSMC technology.
