Abstract
New devices and methods for producing a precision current source or sink with programmable slew rate are disclosed. For example, an electronic circuit capable of providing precision current control including a programmable slew rate is disclosed. For example, the electronic circuit can include a constant current circuit configured to provide a constant current, and a transient current circuit coupled to the constant current circuit at a common electrical node, the transient current circuit configured to sample the constant current of the constant current circuit during a sampling phase, then provide a turn-on programmable slew rate based on the sampled constant current during an active phase.
