Abstract :
A modified input-weighting concept for a c.c.d. recursive filter is proposed; it has been implemented using an m.c.c.d. with a complementary input scheme which provides net weighting coefficients. This improved structure requires neither operational amplifiers nor resistors. The operation and performance of the fabricated 2nd-order bandpass filter are presented.
