| Summary: | New current-mode bandpass filters using three single
outputs inverting second generation current conveyors (ICCII) are
introduced. The first circuit uses two ICCII+ and one
ICCII−, and realizes
an inverting bandpass response. This circuit has one floating
resistor and no independent gain control. The second circuit
uses three ICCII− and
realizes a noninverting bandpass response. The third circuit uses
three ICCII+ and realizes also a noninverting bandpass response.
The second and third circuits employ four grounded resistors and
two grounded capacitors and have independent control on
Q and on the center frequency gain by varying a
single grounded resistor. Spice simulation results using
0.5 um CMOS transistors are included to support the
theoretical analysis. |
