| Abstract: | A SIMO
(single input and multiple
outputs) universal mixed-mode (including
voltage, current, transadmittance, and transimpedance modes) biquad with one
input (a single voltage or current input) and eight outputs (five voltage
outputs and three current outputs simultaneously) by using three differential difference
current conveyors (DDCCs), four resistors, and two grounded capacitors, is
presented in this paper. The proposed biquad filter can realize voltage, current, transadmittance,
and transimpedance modes universal filtering responses (lowpass, highpass,
bandpass, bandreject, and allpass) from the same topology. Moreover, the new mixed-mode
biquad also
features the (i)
use of two grounded capacitors, (ii) orthogonal control of w0 and Q and (iii) high output impedance of three current outputs. H-Spice simulation results
with TSMC 0.25 μm process and ±1.25 V supply voltages verify the theoretical
predictions. |
