A fundamental step in the design of electronic circuits is the verification that they are stable at least on a given set of external terminations, in order to avoid that the solution found be not observable in practice. This is especially true at mic

Source degenerative feedback is extensively applied in the low-noise amplifier design. The beneficial effects of this technique are well established in the open literature. However, the designer is often left to trial-and-error or optimization proced

This article addresses the classical problem of determining the extrinsic resistances ( $R_{G}$ , $R_{S}$ , and $R_{D}$ ) of field-effect transistors (FETs) and, in particular, of high-electron-mobility transistors (HEMTs). The presented approach rel

This letter presents an improved circuit topology to minimize the number of external control voltages that are required to set the state of an N-bit microwave digital attenuator. An alternative method to connect the control signal is proposed. Typica
