Description

一种微能量采集芯片、电路、设备及其控制方法Micro-energy collection chip, circuit, equipment and control method thereof 技术领域Technical field
本申请属于弱能量采集领域，尤其涉及一种微能量采集芯片、电路、设备及其控制方法。This application belongs to the field of weak energy harvesting, and in particular relates to a micro-energy harvesting chip, circuit, equipment and control method thereof.
背景技术Background technique
在弱能量采集领域，能量使用效率很低，以按压采集电路为例，通过按压得到微能量交流电，进而根据微能量交流电生成微能量电压，以一个周期来看，从0V到最高点，最高点的微能量电压由储能电容大小决定。在0V升至2V期间，芯片(包括微处理器和射频芯片)是无法工作的。In the field of weak energy harvesting, the energy use efficiency is very low. Taking the pressing acquisition circuit as an example, the micro-energy alternating current is obtained by pressing, and then the micro-energy voltage is generated according to the micro-energy alternating current. In a cycle, from 0V to the highest point, the highest point The micro-energy voltage is determined by the size of the energy storage capacitor. During the 0V to 2V period, the chip (including the microprocessor and the radio frequency chip) cannot work.
原来的并联电路或者串联电路，只有一个***储能电容(约2.2UF左右)，***储能电容的正极和***储能电容的负极分别电连接在芯片的供电正端和地。在***工作电压低于约2V后，微处理器和射频芯片都停止工作，造成***储能电容里存在残留电荷，微能量交流电不能有效利用，原理上只使用了最高电压到2V之间存储的电荷。The original parallel circuit or series circuit has only one system energy storage capacitor (about 2.2UF), and the positive electrode of the system energy storage capacitor and the negative electrode of the system energy storage capacitor are electrically connected to the positive terminal and ground of the power supply of the chip, respectively. After the working voltage of the system is lower than about 2V, both the microprocessor and the radio frequency chip stop working, resulting in residual charges in the energy storage capacitor of the system, and the micro-energy alternating current cannot be used effectively. In principle, only the storage between the highest voltage and 2V is used. Charge.
因此，传统的微能量采集设备存在无法利用低于微能量电压的能量从而导致地微弱能量采集的阈值高和能量使用效率低的缺陷。Therefore, the traditional micro-energy harvesting equipment has the defects that it cannot use the energy lower than the micro-energy voltage, which results in a high threshold for weak energy harvesting and low energy use efficiency.
