Abstract :
An LC notch filter using on-chip spiral inductors for image-reject applications is described. The filter is designed to allow direct automatic frequency and Q-tuning schemes. The excessive noise generation and linearity degradation of bandpass filters are avoided due to the absence of high-Q poles
