Title: **David D Wentzloff: Innovator in Low-Power Receiver Technology**

Introduction

David D Wentzloff, based in Ann Arbor, MI, is a distinguished inventor with a remarkable portfolio of 32 patents. His work primarily focuses on advancements in low-power receiver technology, significantly impacting the Internet of Things (IoT) sector. Wentzloff’s innovative approaches to wireless communication and secure wake-up systems are paving the way for more energy-efficient devices.

Latest Patents

Among his latest inventions, Wentzloff has developed a low-power standard-compliant NB-IoT wake-up receiver (WRX). This innovative receiver is designed to function as a companion radio to a full NB-IoT receiver, operating exclusively during discontinuous RX modes such as DRX and eDRX. This design enables the full high-power radio to shut down, while the WRX effectively receives NB-IoT Wake-Up Signals (WUS). The fabricated receiver is notable for achieving a power consumption of just 2.1 mW at a sensitivity of -109 dBm, with a bandwidth of 180 kHz across the 750-960 MHz bands. It is constructed using 28 nm CMOS technology, consuming five times less power than previous traditional NB-IoT receivers, marking it as the first dedicated wake-up receiver for the NB-IoT protocol.

Additionally, Wentzloff's patent on a method and system for a low-power and secure wake-up radio enhances communication within wireless sensor networks. This wake-up radio features an analog front end, an analog-to-digital converter, and a digital baseband that generates fast and secure wake-up signals while listening to all channels concurrently.
