Techniques for current mirror circuits |
摘要 |
A circuit includes a current mirror circuit and first and second transistors coupled as a differential pair. A first input voltage is provided to a control input of the first transistor. A second input voltage is provided to a control input of the second transistor. The current mirror circuit includes a third transistor, a fourth transistor coupled to the third transistor, and a fifth transistor coupled in series with the fourth transistor. The third transistor provides a current through the differential pair that is proportional to a current through the fourth transistor. A control input of the fourth transistor is coupled between the fifth transistor and a source of current. |
