Voice-controlled interfaces on acoustic Internet-of-Things (IoT) sensor nodes and mobile
devices require integrated low-power always-on wake-up functions such as Voice Activity …

This article presents the first keyword spotting (KWS) IC that uses a ring-oscillator-based
time-domain processing technique for its analog feature extractor (FEx). Its extensive usage …

This article presents a CMOS 2-in-1 relative humidity (RH) and temperature (Temp) sensor.
A single analog front-end (AFE) interfaces two on-chip transducers and converts the …

This paper presents a ring-type, digitally controlled oscillator (DCO)-based integer-N digital
phase-locked loop (DPLL) that can achieve low jitter and low reference spur concurrently. In …

On-chip oscillators are popular clocking solutions for a wide range of circuits and systems
due to their ease of integration and low form factor, but their energy efficiency is typically …

In distributed radar, a coherent system often gains attention for its higher detection potential
in contrast to its non-coherent counterpart. However, even for a distributed coherent radar, it …

A digital phase-locked loop (DPLL) using the proposed adaptive loop gain controller (ALGC)
is presented. The ALGC uses a spectrum-balancing technique to detect the difference of the …

This brief solves the challenge of loop latency in the digital filter of conventional digital
phase-locked loops (DPLLs), which hinders timely updates of phase frequency detector …

A phase-locked loop (PLL) using a single-ring-oscillator-based integrator with background
frequency calibration is presented. By introducing the single-ring-oscillator-based integrator …

This article presents an injection-locked clock multiplier (ILCM) using a digitally controlled
frequency-tracking loop (FTL) with an integral two-step switched-capacitor (SC) digital-to …
