Abstract: This paper presents an alternative configuration for realizing a canonical voltage-mode first-order allpass (AP) section with electronic tuning. The proposed circuit is composed of only one CCCTA and one floating capacitor, which results in a simple and resistorless structure. Its phase response can be adjusted electronically through the external dc bias currents of the CCCTA. Simulation results based on 0.35 m BiCMOS process parameters with ± 0.75 V supply voltages are provided to demonstrate the performance of the proposed AP section.
