Abstract
A new plus-type second-generation voltage conveyor (VCII+) based first-order mixed-mode (MM) all-pass (AP) filter is proposed in this study. The proposed MM AP filter employs two VCII+s, three resistors and one grounded capacitor. It has low input and high output impedances for the current-mode selection while it has low input and low output impedances for the transimpedance-mode selection. The AP filter gain is unity for the current output while it is adjustable for the voltage output via a grounded resistor. However, a single passive component matching condition is needed for the proposed MM AP filter. Complete non-ideal analysis by taking into account all the parasitic resistors and non-ideal gains of the VCII+ is performed. The presented theory is verified through SPICE simulations by using supply voltage of ± 0.9 V and 0.18 µm Taiwan Semiconductor Manufacturing Company complementary metal oxide semiconductor technology parameters. © The Institution of Engineering and Technology 2020
