Current source circuit for generating a low-noise current and method of operating the current source circuit |
摘要 |
A current source circuit for generating a low-noise current has a current mirror circuit with a first and a second transistor. The current mirror circuit contains a capacitor connected between a source connection and a gate connection of the second transistor. The current mirror circuit likewise contains a switching element disposed between a drain connection of the first transistor and the gate connection of the second transistor. The switching element may be controlled as a function of an operating state of the current source circuit.
