“…To foster a better comparison between the architectures, receiver sensitivity can be normalized to the same data rate, in this example arbitrarily chosen as 100 kbps. The normalized sensitivity can be derived for each receiver since data rate scales linearly with bandwidth and thus inversely with sensitivity [58]: Sensitivity @100kbps D Sensitivity 10 log 10 Data Rate 100 kbps For example, a 10 times increase in data rate would result in 10 dB higher sensitivity. Figure 19 shows a plot of normalized sensitivity at 100 kbps versus power consumption.…”

Design of radios with ultra-low-power consumption can enable many new and exciting applications ranging from wearable healthcare to Internet of Things devices and beyond. Achieving low power operation is usually an exercise in trading-off important performance metrics with power. This chapter presents an overview of state-of-the-art narrowband architectures and techniques that achieve ultra-low-power operation, and concludes with a section that benchmarks recent state-of-the-art designs in order to illustrate power-performance trade-offs.

Abstract-This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative architecture is used. An integrated circuit, implemented in a CMOS 0.18-m technology and operating with a 1.5-V power supply, exhibits energy consumption of 0.24 nJ/bit with a measured sensitivity of 66 and 61 dBm at 3.494 and 3.993 GHz, respectively, with a BER of . Also included on the integrated circuit is an automatic tuning circuit based on a digital phase-locked loop that is used to set the resonant frequency of the super-regenerative block.Index Terms-Digital phase-locked loop, oscillator, receiver architecture, super-regenerative system, ultra-wideband communication, wireless sensor network.

“…What are the merits of using biological organisms for living machines compared with entirely man-made ones? Living organisms, especially insects, possess many excellent properties, including outstanding and unparalleled agility of locomotion, which has made insects among the top focuses in the development of autonomous robots for decades [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Employing living insects as the platform for legged machines by electrical stimulation on leg muscles to induce user desired motor actions and behaviors leads to significant power-saving.…”

Most of the stimulation protocols proposed and tested were conducted in open-loop control manner [4][5][6][7][9][10][11]. Those researches focused on developing effective stimulation protocols, e.g.…”

Steering motor units (e.g. legs) of a living organism by controlled stimulation protocols is a key performance toward living machines, biohybrid robots, or cyborg animalsa fusion of living organisms and man-made devices. To achieve fundamental locomotion pattern generation (e.g. walking gait), a closed-loop (feedback) control system to steer motor units to be set at or to move along a predetermined position and motion path is essential. This study demonstrated the capability to build a precise closed-loop control system manipulating the angular displacement of a coleopteran's leg with electrical stimulation applied directly to the corresponding muscles. We confirmed the correspondence between the angular displacement of the beetle's leg and the electrical stimulation frequency was proportional, nonlinear, and time-variant. A fuzzy control system with multiple membership functions using a proportional controller with adjustable parameters was then proposed and adopted for motion control, and we successfully steered a living leg along a predetermined motion path.
