Extended Data Fig. 7: Schematic of power measurement circuit and an example of measured data.
From: Analogue speech recognition based on physical computing
A digital-to-analogue converter (DAC), source measure unit (SMU), and the RNPU are connected in series. For each electrode, the specified voltage is applied by the DAC, and the current is measured with a source measure unit. The measurement is repeated sequentially for each electrode. The average static power consumption is calculated as: \( < {P}_{static} > ={\sum }_{k=0}^{7}{V}_{k}{I}_{k}=1.9\pm 0.5\) nW.
