S- Parameters and Impedance Transformers

For high speed circuits with transmission lines, achieving maximum power transfer is important-Maximum power transfer coincides with having zero reflections (i.e., L = 0) Can we ever win on both issues? Voltage Power 25

Subthreshold Operation and gm/Id design - CppSim

Transconductance in Subthreshold Region Assuming device is in subthreshold and in saturation: 12 Id Vgs Id_op Vds > 100mV M1 Id Vgs NMOS g s d gm = ΔV gs ΔId Vgs_op Vgs_op ⇒ gm = δId δVgs ≈ID0 W L eVgs/(nVt) 1 nVt = Id nVt Recall for strong inversion : gm ≈ 2Id (Vgs −VTH) ID ≈ID0 W L eVgs/(nVt) g m purely a function of I d!
