The bilinear design of high-pass switched-capacitor (SC) ladder filters is considered, via the variable z→-z transfomation in a properly designed SC low-pass ladder section . This allows to maintain the same ladder topology of integrators as in the original design and, than, to ensure similar stability and sensitivity characteristics. Numerical and experimental results from a breadboarded high-pass SC filter are reported.
