摘要：
In this paper, a modified CDTA (MCDTA) is presented and the current-mode second-order band-pass, high-pass notch, and low-pass notch circuits using MCDTAs are given. Moreover, a current-mode sixth-order elliptic hand-pass filter is realized by means of cascade method. Having used six MCDTAs, one CDTA six grounded capacitors and two resistors, the circuit is easy to be integrated, of which the parameters can be electronically adjusted by tuning bias currents. It is noted that the results of circuit simulations are in agreement with theory.
