Abstract
A second generation integrator based on the switching current memory cell reported in (Gonçalves, 1996 A) has been prototyped. The constant voltage switching of the integrator is well suited to low voltage applications, since it avoids the conduction gap of the switches as well as the signal dependent charge injection. A programmable biquad has been implemented using the proposed second generation integrator. The center frequency and the quality factor can be tuned independently.
