Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IA.
I
Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IB.
Vomax Output dynamic range
Decrease V1 gradually, and measure the voltage when the
waveform output is distorted. The voltage is called VOL.
Next, increase V1 gradually, and measure the voltage when the
top of waveform output is distorted. The voltage is called VOH.
Voltage Vomax is calculated by the equation below:
Vimax Maximum input
Increase the input signal (SG2) amplitude gradually, starting from
700mV
output signal starts becoming distorted.
