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 that of the usual ... Depending on your application, you can optimize each circuit's dynamic ...

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 ...

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 ...

ROHM has developed a linear op amp – LMR1901YG-M – featuring, it claims, the lowest current consumption in the industry. This makes it suitable for amplifying sensor signals used to detect and measure ...

Even the worst op amp you can buy is probably better than something you have the patience to design in a few minutes with a FET or a bipolar device. Fair to say that we do enjoy these oddball op ...
