| Description | In this paper, a new realization of electronically tunable voltage output second-order low-pass (LP) and band-pass (BP) filter is presented. The circuit has a multiple-input single-output structure, and LP and BP outputs are provided using the same structure. One electronically variable second-generation voltage conveyor (VCII), whose impedance at the Y port can be electronically varied using a control current $(I_{con}$), two capacitors, and one resistor are used. By changing the value of $I_{con}$, the impedance value at the Y port can be electronically varied; therefore, the value of $ω_{0}$ can be tuned. This feature helps to reduce the number of passive components used. Interestingly, the LP and BP outputs are provided at the low-impedance Z port of the VCII, and there is no need for an extra voltage buffer for practical use. The circuit enjoys a simple realization consisting of only 24 MOS transistors. Simulation results using PSpice and 0.18 μm CMOS parameters are provided. The value of $ω_{0}$ can be varied from 1.2 MHz to 1.7 MHz, while $I_{con}$ varies from 0 to 50 µA, with a power consumption variation from 244 µW to 515 µW. |
