AC Test Circuit
PC Board Layout
The frequency response of this circuit depends greatly on
the care taken in designing the PC board.
The use of low
inductance components such as chip resistors and chip
capacitors is strongly recommended, while a solid
ground plane is a must!
Attention should be given to decoupling the power supplies.
A large value (10μF) tantalum in parallel with a small value
(0.1μF) chip capacitor works well in most cases.
Keep input and output traces as short as possible, because
trace inductance and capacitance can easily become the
performance limiting items.
