Abstract

This paper presents new floating inductance simulator based on three electronically controllable current conveyors (ECCIIs) and differential voltage buffer (DVB). The inductance simulator offers simple electronic control of inductance value as well as simple control of losses by change of parameters of active elements. Based on this floating inductance simulator, example of reconnection-less reconfigurable pseudodifferential first-order filter, allowing change of transfer function between high-pass and inverting all-pass response, is discussed and studied. Moreover, the proposed structure can be easily extended to a pseudo-differential second-order band-bass filter. Behaviour of presented solutions is verified by PSpice simulations and also experimentally in frequency band up to 10 MHz. Obtained results confirmed expected features.
