Abstract :
A CMOS third order elliptic low-pass filter with a 110MHz cut-off frequency realized in a 3μm-process is presented. The filter consists of differential transconductance elements and capacitors. The transconductance element has good linearity properties and an excellent high frequency behaviour thanks to the absence of internal nodes. Both the cut-off frequency and the Q-factors can be tuned.
