Generally, the core of an IoT device is a Microcontroller (MCU) and a wireless Transmitter/Receiver (Tx/Rx).
minimum level of energy and power. The power cycle of a miniaturized IoT device has two operation modes: long-duration sleep mode and short-duration active mode. Thus, it is critical to reduce the standby power consumption of the always-on blocks and to design energy-efficient circuits for both modes.
Therefore, an ultra-low power system is an essential component for battery-based miniaturized IoT devices. In addition, novel ultra-low power circuit techniques should be developed to minimize the energy per operation and the power consumption of the miniaturized IoT device. transmitter for implantable application.
