Abstract
This paper describes a digital-friendly passives-less time delay cell that generates programmable phase-shifts for down converting front-end in LO-based beamsteering receiver. Cell design supports 1.5–6.5GHz broadband receiver operation and cell layout occupies an area of only 15×16.5μm 2 including power supply rails and control logic. Simulated in 28nm CMOS technology, delay cell exhibits 6 distinct delay values {3, 3.5, 17, 19, 24, 43}ps consuming at most 220μW@IV.
