| Abstract: | The current-mode universal biquadratic filter with three inputs and single
output (TISO) using single multi-output current followers (MO-CF) has been
described. Based on the use of the second-generation current-controlled
conveyor working as the MO-CF, the proposed circuit contains only one MO-CF,
one resistor and two grounded capacitors, therefore, offers electronic tuning
possibilities. It can realize all of the five standard biquadratic filtering
functions, all at a high impedance output. The present filter also provides an
independent control of the natural angular frequency  and bandwidth (BW) by adjusting an external dc
bias current and has active and passive component sensitivities. |
