The cell is the 8rd order Butterworth low pass filter with cut-off frequency adjustment. The block has two channels of differential inputs and outputs and based on a pseudodifferential circuit and Sallen-Key circuit. CO frequency can be set by the digital code.
The block is fabricated on TSMC 0.18 um technology.
