Low-voltage and low-power fractional-order parallel tunable resonator


A novel implementation of a fractional-order parallel resonator, capable of operating in a ±0.5 V power supply voltage environment, is presented in this work. Compared to the corresponding already published structures, it offers the benefit of reduced circuit complexity, due to the utilization of very simple voltage-mode 1st-order filter sections, leading also to reduction in the dc power consumption. Electronic tuning capability is another attractive feature of the proposed structure achieved using programmable MOS transistor transconductance parameters. © 2019 Elsevier Ltd
