چکیده
For true low-power peer-to-peer wireless links for sensing, link symmetry must be maintained unlike in [1,2] where the burden is shifted to the receiver. In addition, the transceiver power dissipation and performance should be adaptive to save power when the link distance is short. We present a 120μW MICS/ISM band receiver with -90dBm sensitivity at a data-rate of 200kb/s with BER<0.1%. The receiver incorporates a 44μW low-power (LP) mode that achieves -70dBm sensitivity at 200kb/s and 0.1% BER. At a lower data-rate of 20kb/s, the LP mode can be used as a wake-up receiver with increased sensitivity of -75dBm with 1% BER and 38μW power consumption.

A 90μW MICS/ISM Band Transmitter with 22% Global Efficiency
For fully autonomous implantable or body-worn devices running on harvested energy, the peak and average power dissipation of the radio transmitter must be minimized. We propose a highly integrated 90μW 400MHz MICS band transmitter with an output power of 20μW leading to a 22% global efficiency — the highest reported to date for such systems. We introduce a new transmitter architecture based on ...
متن کاملA 3 μW, 400 MHz Divide-by-5 Injection-Locked Frequency Divider with 56% Lock Range in 90nm CMOS
An ultra-low power injection locked frequency divider (ILFD) is presented and demonstrated. Based on a 5-stage single ended ring oscillator, the ILFD achieves a lock range of 56% at a division ratio of 5 in the medical implant communications service (MICS) and the 433MHz ISM frequency bands. The ILFD is implemented in a 90nm CMOS process. It consumes 3 μW of power from a 1.0V supply and 100 μm ...
متن کاملA 3.3 µW dual-modulus frequency divider with 189% locking range for MICS band applications
This paper presents the design and simulated performance of an ultra-low-power 4/5 frequency divider based on a CMOS ring oscillator. The divider operates over a 189% locking range (29MHz – 1GHz) for both division ratios, covering the MICS band and 433MHz and 915MHz ISM bands while consuming only 3.3 μW in MICS band. The wide locking range and low power consumption makes this very suitable for ...
متن کاملFractal Bandpass Filter Using Y-shaped Dual-Mode Resonator for C-Band Receiver (Research Note)
In this study, a fractal, Y-shaped dual-mode resonator bandpass filter (BPF) with input-output cross-coupling is introduced. A parallel-coupling feed structure with a cross coupling has been used to generate two transmission zeroes (TZs) near the lower and upper cutoff frequency that can effectively improve the passband edge selectivity. Also, a fractal shaped based on conventional diamond and ...
متن کاملOOK Super-Regenerative Receiver for Medical Implant Communications
Recent advances in the medical field are spurring the need for ultra-low power transceivers for wireless communication with medical implants. To deal with the growing demand for medical telemetry, the FCC commissioned the Medical Implant Communications Services (MICS) standard in 1999 in the 402–405 MHz band. This paper presents a 350 W FSK/MSK direct modulation transmitter and a 400 W OOK supe...
