From: A design and implementation of low-power ultrasonic water meter

notationDescription
EMCUSupply voltage of the STM32L162 microcontroller (MCU)
EFESupply voltage of the MAX35101 front-end chip (FE)
\( {I}_{active}^{MCU} \)Current consumption of the MCU in the run mode (active state)
\( {I}_{active}^{FE} \)Current consumption of the FE in the active state
\( {I}_{idle}^{MCU} \)Current consumption of the MCU in the idle mode (idle state)
\( {I}_{idle}^{FE} \)Current consumption of the FE in the idle state
\( {T}_{active}^{MCU} \)Operating time of the MCU in the active state
\( {T}_{idle}^{MCU} \)Operating time of the MCU in the idle state
