Hierarchical Duty-Cycling of Wireless Sensors
2019 28th International Conference on Computer Communication and Networks (ICCCN), 2019Energy efficiency is critical in many IoT applications with sensors that deliver data over wireless communications. Duty-cycling has been a major method for reducing energy consumption. One popular duty-cycling is MAC duty-cycling where an MCU commands the periodic or adaptive turning on and off of an RF chip.

Design of A 0.8GHz-3GHz Duty-Cycle Corrector With a 20%-80% Input Duty Cycle
2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019An analog duty cycle correction circuit using a novel pulsewidth modification cell. We correct the duty-cycle by changing the phase of the voltage. Our calibration allows the input duty cycle to range from 20% to 80%, and the circuit corrects the duty cycle to 50%.

A voltage-controlled duty-cycle oscillator
IEEE Journal of Solid-State Circuits, 1990A voltage-controlled duty-cycle oscillator (VCDCO) developed for use with integrated silicon sensors is described. The circuit's transfer function is, to first order, completely independent of component values. Measured results indicate that the circuit is capable of resolving input voltage changes as small as 6 mu V in a 2000- mu s period and has a ...

Synchronous duty cycle correction circuit
2010 18th IEEE/IFIP International Conference on VLSI and System-on-Chip, 2010A duty cycle correction (DCC) circuit with deterministic clock insertion delay is presented. To neutralize the ambiguity of the DCC circuit insertion delay induced by the wide range of input clock duty cycle, a signal differentiating circuit at the input of the circuit is used which narrows the input duty cycle range to the circuit core.

Clock buffer with duty cycle corrector
Microelectronics Journal, 2010A clock buffer with duty cycle corrector circuit is presented. The proposed circuit can generate either 50% duty cycle or conserve the duty cycle as input clock. It corrects the input duty cycle of 10-90% for generated 50% duty cycle of output clock with error less than 0.9%.

Impact of Duty Cycling on Opportunistic Communication
IEEE Transactions on Mobile Computing, 2016A major challenge in mobile wireless devices for opportunistic networks is to decrease the energy consumption. The decrease should not come at a cost of reduced application throughput (i.e., goodput). This work evaluates the potential performance gains for mobile nodes that adopt duty cycling in an opportunistic context.

Adaptive duty cycling for energy harvesting systems
Proceedings of the 2006 international symposium on Low power electronics and design - ISLPED '06, 2006Harvesting energy from the environment is feasible in many applications to ameliorate the energy limitations in sensor networks. In this paper, we present an adaptive duty cycling algorithm that allows energy harvesting sensor nodes to autonomously adjust their duty cycle according to the energy availability in the environment.
