Abstract EN
This paper introduces a new current-mode (CM) universal biquad filter structure with optimum number of active and passive elements.
In the design, the proposed circuit uses a single active element namely, current follower trans-conductance amplifier (CFTA) and two grounded capacitors as passive elements.
The main feature of the proposed circuit is that it can realize all five standard filtering functions such as low pass (LP), band pass (BP), high pass (HP), band stop (BS) and all pass (AP) responses across an explicit high impedance output terminal through the appropriate selection of three inputs.
In addition, the same circuit is also capable to simultaneously realize three filtering functions (LP, BP and HP) by the use of single current input signal.
Moreover, the proposed structure is suited for low voltage, low power operations and offers the feature of electronic tunability of pole-frequency and quality factor.
Further to extend the utility of the proposed circuit block higher order current-mode filters are also realized through direct cascading.
A detailed non-ideal and parasitic study is also included.
The performance of the circuits has been examined using standard 0.25 μm CMOS parameters from TSMC.
