[ 6 ] Test circuit

1) To observe waveform and current

2) Condition

(1) Oscilloscope

• Bandwidth should be 5 times higher than DUT’s output frequency.

• Probe ground should be placed closely from test point and lead length should be as short as possible.

(2)

By-pass capacitor (approx. 0.01

F󲸝0.1

F) should be placed closely between Vcc and GND

(3) Use the current meter whose internal impedance value is small.

(4) Power supply

• Start up time

(0 V→90 %Vcc)

of power source should be more than 150 us.

• Impedance of power supply should be as low as possible.
