470-MHz-698-MHz IEEE 802.15.4m Compliant RF CMOS Transceiver

Low-Power Direct Conversion Transceiver for 915 MHz Band IEEE 802.15.4b Standard Based on 0.18 μm CMOS Technology

Trung-Kien Nguyen et al. 33 This paper presents the experimental results of a lowpower low-cost RF transceiver for the 915 MHz band IEEE 802.15.4b standard. Low power and low cost are achieved by optimizing the transceiver architecture and circuit design techniques. The proposed transceiver shares the analog baseband section for both receive and transmit modes to reduce the silicon area. The RF...

190-MHz CMOS 4-Kbyte Pipelined Caches

In this paper we describe the design and implementation of a 190-MHz pipelined 4-Kbyte instruction and data cache. The caches are designed in 1.0-μm CMOS and measure 0.78 x 0.47 cm2. This paper describes the microarchitecture, cache timing, circuit implementation, and layout of both the instruction and the data cache. The key features of these caches are pipelined execution and the use of dynam...

IEEE 802.15.4 transceiver for the 868/915 MHz band using Software Defined Radio

This paper reports an implementation of the PHY specifications of the IEEE 802.15.4 standard for the frequency band 868/915 MHz on a Software Defined Radio (SDR) platform. This standard is defined for low power, low data rate and low cost wireless networks. These specifications are used by the Zigbee technology for various applications such as home automation, industry monitoring or medical sur...

70 MHz CMOS Gm - C Bandpass Filter

This paper discusses a shunt active ûlter intended for installation on a power distribution system. The active ûlter has an additional capability to regulate the distribution line voltage by means of adjusting reactive power. Theoretical analysis investigates the dynamic performance of combined harmonic damping and voltage regulation. As a result, harmonic damping makes it possible to improve t...
