Abstract :
A new design concept of low noise negative resistance circuit is presented considering stability conditions. Low noise properties of a negative resistance circuit are guaranteed by an optimal value of the transistor feedback. Based on this circuit, a low-noise 2/sup nd/-order 3 GHz active bandpass filter has been designed and fabricated.
