2 MHz BIQUAD BAND-PASS FILTER
0.01% 10V STEP
VS = ±15V
NEG SLOPE
The circuit in Figure 48 is commonly used in medical imaging
ultrasound receivers. The 30 MHz bandwidth is sufficient to
accurately produce the 2 MHz center frequency, as the measured
response shows in Figure 49. When the bandwidth of the op
amp is too close to the center frequency of the filter, the internal
phase shift of the amplifier causes excess phase shift at 2 MHz,
which alters the response of the filter. In fact, if the chosen op
amp has a bandwidth close to 2 MHz, the combined phase shift
of the three op amps causes the loop to oscillate.

Careful consideration must be given to the layout of this circuit
as with any other high speed circuit.

10 V Step Input (Negative Slope)
If the phase shift introduced by the layout is large enough, it can
alter the circuit performance, or worse, cause oscillation.
