ABSTRACT:
Methods and systems for increasing gain for an electric circuit may include receiving an input differential signal at a first configured pair of transistors and a second configured pair of transistors. The first and second configured pair of transistors may be inductively loaded. The first configured pair of transistors may be self-biased via the inductive loading. DC current may be generated via the second configured pair of transistors. The first and/or the second configured pair of transistors may be configured as input transconductors. A pair of inductors may be configured for the inductive loading and the configured pair of inductors may be tapped for the self-biasing. If the first configured pair of transistors comprises NMOS transistors, then the second configured pair of transistors may comprise PMOS transistors.
