Abstract :
Beamforming electromagnetic waves, especially at close range, is challenging. Extremely accurate control of phase/timing is required. In this work we present a digital programmable delay-line suited for transmission beamforming using multiple senders. Back-gate tuning of inverter delays are measured to give relative temporal tuning in the range of 1.1 ps.
