Abstract: | In this letter, a new voltage-mode (VM) configuration for providing low-power and simultaneous realization of first-order
low-pass, high-pass and all-pass filters is presented. The output of the all-pass filter is taken differentially. The proposed
circuit contains low number of components, i.e., only two NMOS transistors, a floating battery, a grounded capacitor and a
floating resistor. Adding two NMOS transistors to the proposed circuit it is modified as an all-pass filter with a single-ended
output. The main advantage of the presented circuits in comparison with other counterparts is their extremely low power dissipation.
Moreover, the floating resistor can be replaced with an additional NMOS transistor in triode region to provide electronic
tunability. Simulation results using SPICE program are given to demonstrate the performance of the proposed circuit. |
