A bi-directional current source for a grounded load will always have some complication in its construction. The improved Howland Current Pump as shown in Figure 1 is the most frequent choice for this ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

In many applications such as computing, the power rail’s load transient requirement are becoming more and more restrictive. Furthermore, because it involves complex Laplace transfer function ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...
