ACTIVE BIAS CONTROLLER
Full Featured Evaluation PCB
Careful PCB layout is critical to achieve stable and
low noise operation. The negative voltage genera-
tor charge pump stage requires particular attention.
To isolate the charge pump switching noise from the
analog circuit blocks, create two separate ground
planes dedicated to AGND and DGND connections.
Connect AGND (pin#17) and DGND (pin#16) pins to
the paddle at a single point under the package. Con-
nect all the components connected to the charge
pump (D1, C12 and C14 in the application circuit) to
DGND plane, and connect rest of the external compo-
nents to a low noise AGND.
