Fig 1. The standard Howland Current Pump (HCP) is a current source that can generate both positive and negative current. Fig 2. Adding a boost circuit to an HCP design allows for higher output current ...
Planar spiral inductors are less expensive than eitherchip or coil inductors for PCB (printed-circuit-board)-based designs. Accuracy in designinga spiral inductor is important because it isdifficult ...
