Ibrahim Kasim

Research overview

Ibrahim researches the linearization of active inductors for predistortion circuits. Active inductors can replace large passive structures in compact integrated implementations, but their useful tuning range, noise, nonlinearity, stability, and process sensitivity must be understood together.

The project renews MOSAIC’s longstanding work on broadband circuit design, optical and RF link correction, and predistortion. It asks how a compact circuit block can supply the intended frequency-dependent behaviour without creating a new distortion mechanism that overwhelms the benefit.

Place in MOSAIC

Ibrahim’s work connects three parts of the group:

• Signal propagation, because the target is correction of a physical channel or interface
• Circuits and interconnect, because the correction is embodied in an integrated analog block
• Silicon realization, because layout, parasitics, bias, stability, and verification determine whether the concept survives implementation

Current direction

This page will expand with the selected topology, modelling approach, design constraints, simulation evidence, physical implementation, and measurement strategy as the project progresses.
