摘要：
Novel voltage- and current-mode multifunctional biquads using OTAs are presented. The proposed circuits utilize only three OTAs and two capacitors. The voltage-mode circuits are capable of realizing three different simultaneous responses; while the current-mode version can realize four filtering outputs (lowpass, bandpass, highpass and notch) simultaneously.
