The op-amp current source attributed to Brad Howland of MIT is used widely and is familiar in circuit design. Yet it can be difficult to understand for those not close to it. The following explanation ...

The circuit in Figure 1d describes a bipolar current source with a simpler feedback configuration than ... circuit's dynamic impedance and current range through a judicious choice of op amps and ...

The gate is biased at ground potential through the inductor, and the source is held above ground by the current ... amplifier. The input of a high-performance op-amp will almost certainly be a FET ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

Linear Technology has introduced new single and dual 4GHz FET-input op amps for high dynamic ... range capabilities of this ultralow bias current op amp family for applications with a gain of ...

So if the load is set to 10 A and you connect it to a 12 V source, the MOSFET should look like a ... it does mean you have to carefully select the op amps to have very low input offset voltage ...

ROHM has developed a linear op amp – LMR1901YG-M – featuring, it claims, the lowest current consumption in the industry ... and other parameters in applications powered by internal sources (i.e.
