Semiconductor circuits capable of mitigating unwanted effects caused by input signal variations |
摘要 |
Semiconductor circuit capable of mitigating unwanted effects caused by variations in a received input signal are provided, in which a main circuit receives an input signal and comprises a first current source coupled between a first node and a first power voltage to generate a first current according to a first bias voltage. A replica circuit is coupled to the main circuit to duplicate a variation in a voltage at the first node caused by a variation in the input signal and dynamically adjusts the first bias voltage according to the duplicated variation such that the first current is maintained at a constant. |
