Abstract:

This article presents a 2.4 GHz receiver with a third-harmonic time-interleaved passive mixer and reconfigurable analog finite-impulse-response (AFIR) filter. To improve linearity while maintaining low power consumption, a 6-path third-harmonic time-interleaved mixer with a 6-phase non-overlapping local oscillator (LO) is proposed, employing capacitive stacking and charge sharing techniques to enhance in-band …

Abstract:

This article presents an event-driven discrete-time level crossing analog-to-digital converter (DT-LCADC) that is energy-efficient in converting both sparse and generic signals and is robust against process voltage and temperature (PVT) variations. The proposed DT-LCADC uses the comparator delay to classify each level-crossing event as slow (produced by a small input …
