This work exploits the well-known gmover IDmethodology to develop a novel approach to optimize the design of regulated cascode amplifiers (RgC). The proposed design framework starts extracting a set of lookup tables describing the circuit's figures of merit as a function of the gmover IDratio. Due to the feedback topology of the circuit, the performances, in terms of bandwidth, gain, and DC power consumption, exhibit a behavior that is counter-intuitive with respect to the typical tradeoffs suggested by the gm/IDtheory. The proposed method is validated designing a RGC with the 0.13 Î¼m IHP SiGe process. The performance of the proposed solution are obtained through post-layout simulations.
