Abstract
The present invention describes the method and system of applying filter synthesis technique to distributed amplifier design. The method for synthesizing a distributed amplifier comprises the steps of determining an appropriate filter design characteristic, computing inductor and capacitor values, converting the equivalent values into a distributed amplifier with response characteristics that mirror that of the chosen filter. Applying filter synthesis techniques to distributed amplifier design results in predictable amplifier response characteristics. Filter synthesis techniques are used to design filters with controllable characteristics such as gain, cut-off frequency, and roll-off slope. Depending on the desired filter characteristics, appropriate inductor and capacitor sizes can be determined. Transferring these chosen inductors and capacitors sizes to the distributed amplifier results in amplitude and phase responses that behave like a preferred embodiment or prototype filter.
