Wireless communication with AM (Amplitude Modulation) is widely used. If the power consumption of the AM receiver is reduced to the utmost limit, the power source can be replaced with an energy harvest, which is very convenient. Power lines will not be needed and batteries will no longer need to be replaced or recharged. Therefore, we propose an ultra-low power demodulation circuit for AM receivers. The proposed demodulator achieved a peak SNDR of 47.8 dB and a power consumption of 3.36 μW at a carrier frequency of 1 MHz. © 2022 Institute of Electrical Engineers of Japan.

用于 AM 接收器的基于逆变器的超低功耗解调电路

使用 AM（调幅）的无线通信被广泛使用。如果调幅接收机的功耗降到极限，可以用能量采集器代替电源，非常方便。不再需要电源线，也不再需要更换电池或充电。因此，我们提出了一种用于 AM 接收器的超低功耗解调电路。所提出的解调器在 1 MHz 的载波频率下实现了 47.8 dB 的峰值 SNDR 和 3.36 μW 的功耗。© 2022 日本电气工程师协会。由 Wiley Periodicals LLC 出版。
