Voltage Controlled Filters
OTA’s are extremely useful for implementing voltage con-
trolled filters, with the LM13600 having the advantage that
the required buffers are included on the I.C. The VC Lo-Pass
Filter of Figure 11performs as a unity-gain buffer amplifier at
frequencies below cut-off, with the cut-off frequency being
the point at which X
/g
equals the closed-loop gain of
(R/R
). At frequencies above cut-off the circuit provides a
single RC roll-off (6 dB per octave) of the input signal ampli-
tude with a 3 dB point defined by the given equation, where
g
is again 19.2 x I
at room temperature. Figure 12
shows a VC High-Pass Filter which operates in much the
same manner, providing a single RC roll-off below the de-
fined cut-off frequency.
Additional amplifiers may be used to implement higher order
filters as demonstrated by the two-pole Butterworth Lo-Pass
Filter of Figure 13 and the state variable filter of Figure 14
Due to the excellent g
tracking of the two amplifiers and the
varied bias of the buffer Darlingtons, these filters perform
well over several decades of frequency.
