Control circuit employing follower circuit to control reference signal and related circuit control method |
| 摘要 |
A control circuit includes: a first current generating circuit arranged for generating at least one output current according to a reference signal; a second current generating circuit arranged for generating a reference current corresponding to the reference signal according to the reference signal; and a follower circuit coupled to the second current generating circuit for generating a control current according to the reference current, and feeding back the control current to the first current generating circuit from the second current generating circuit in a signal-following manner to control the reference signal. |
