“…Table 4 shows the maximum activation distance of the prototypes in various configurations. The cascoded method has the lowest range at 7 m, which is still greater than most previous works [7][8][9][10][11]. Increasing the number of charge pump stages and photodiodes yields a range of 25 m. At such distances, the laser's beam width becomes noticeable, which helps with aiming but dilutes the incident light energy on each photodiode.…”

“…Several works proposed zero standby solutions that harvest and utilize an optical wake-up signal [7][8][9][10][11][12][13][14][15][16][17]. These solutions have mainly been proposed for eliminating standby consumption in infrared (IR) receivers and processing units for set-top boxes.…”

“…Kang et al [9] developed a circuit to harvest power from a 15 mW IR laser to drive an electromechanical relay, but their prototype had a similar range of 2 m. Rosa et al [10] also developed a relay-based architecture with a range of 2.5 m that could be extended to 7 m with a precisely positioned Fresnel lens. Utsunomiya et al [11] demonstrated a harvesting circuit on a low-voltage integrated process that could be woken from 6 m by a 50 mW IR transmission. While their design is impressive in both range and power, it requires custom integrated hardware and is mainly intended for low-voltage battery-powered applications.…”

Despite recent efforts to reduce standby power consumption in plug loads, new trends in the miniaturization and wide distribution of electronics necessitates devices with zero standby consumption. This work introduces two zero standby solutions that wake a device using an external input of energy harvested from a 5 mW laser pointer. These solutions are applicable to electronics that are remotely activated or have a fiber optic connection. The first utilizes a cascoded header switch to allow for simultaneous low-voltage harvesting and high-voltage blocking. The second involves the use of a charge pump to boost the harvested voltage to a level appropriate for the gate of a high-voltage switch. Prototypes for each method are developed in order to demonstrate functionality and identify the associated benefits and drawbacks. The results show that combining the two methods allows for optimal activation range (up to 25 m) and component count.

“…Many of these solutions require an external wake-up signal to activate. Various zero-standby solutions in previous works generate their wake-up signal optically with infrared [21][22][23][24][25][26][27][28] or lasers [29,30], mechanically with switches [31] or piezoelectric devices [32][33][34], thermally with thermistors [35] or peltier devices [36], or through passive RF (radio frequency) transmission [37][38][39][40]. Near-zero standby solutions use an ultra-low-power receiver to process the wake-up signal.…”

Despite technical advances in efficiency, devices in standby continue to consume up to 16% of residential electricity. Finding practical, cost-effective reductions is difficult. While the per-unit power consumption has fallen, the number of units continuously drawing power continues to grow. This work reviews a family of technologies that can eliminate standby consumption in many types of electrical plug loads. It also investigates several solutions in detail and develops prototypes. First, burst mode and sleep transistors are established as building blocks for zero-standby solutions. This work then studies the application of two types of wake-up signals. The first is from an optical transmission, and is applicable to remote-controlled devices with a line-of-sight activation, such as set-top boxes, ceiling fans, and motorized curtains. The second is from a wake-up radio, and is applicable to any wireless products. No single technology will address all standby power situations; however, these emerging solutions appear to have broad applicability to save standby energy in miscellaneous plug loads.

“…The rising and falling edge detector [100], [101], and [102] are used to detect the moment when V AC crosses V REC . For the rising edge detector, it is desired to have a fast response when V AC surpasses V REC to maximize the conduction time of N 1 or N 2 .…”
