Single-Supply Twin T Chebyshev High Pass Filter

Problem:
How does a designer make a Twin T high pass Chebyshev filter that operates from a Single-Supply?

Solution:
Use the circuit below:



This circuit has a fixed gain of 1 (0 dB) and 3 dB ripple. For other levels of ripple, call Texas Instruments Applications.

The designer, if not familiar with the topics, may want to review Coupling Capacitors (Cin in the schematic) and Virtual Grounding (Vcc/2 in the schematic).
