Abstract :
This paper describes a high performance CMOS transconductor with a linearity-improved V-I conversion stage, a novel output stage which allows us to boost the output resistance without bandwidth penalty and a symmetric CMFB system to enhance the CMFB loop gain and to improve CMFB´s linearity. A 3 MHz fifth-order elliptic low-pass filter is designed using the proposed transconductor
