Low Noise Integrator
The Circuit in Figure 10implements a deBoo integrator. Inte-
gration linearity is maintained through positive feedback. The
CLC5801’s low input offset voltage and matched inputs al-
lowing bias current cancellation provide for very precise inte-
gration. Stability is maintained through the constraint on the
circuit elements.
High-Gain Sallen-Key Active Filters
The CLC5801 is well suited for high-gain Sallen-key type of
active filters. Figure 11 shows the 2nd order Sallen-Key low
pass filter topology. Using component predistortion methods
as discussed in OA-21 enables the proper selection of com-
ponents for these high-frequency filters.
Low Noise Magnetic Media Equalizer
The circuit in Figure 12 implements a high-performance
low-noise equalizer for such applications as magnetic tape
channels. The circuit combines an integrator with a band-
pass filter to produce the low-noise equalization.
The circuit’s simulated frequency response is illustrated in
Figure 13
