Witryna30 maj 1994 · This paper presents an optimized design for the Wilson and improved Wilson MOS current mirrors. The paper includes a detailed analysis of the high-frequency behaviour of the Wilson and improved Wilson MOS current mirrors, which shows a current transfer function with two poles and one zero. WitrynaA current mirror with a MOS transistor to compensate for the base current A bipolar transistor with a split-collector can be used to improve the current match between the input and output of the current mirror [3]. The split-collector current mirror structure is shown in Figure 5. A single split-collector transistor Q4 is used in this structure.

Witrynaso the overall frequency response should be carefully exam-ined. However, since the small-signal resistance at the drain of M13 or M14 is small, the extra pole at that node locates at high frequency. Therefore, it does not signiﬁcantly affect the frequency response, especially if the load capacitor is large. Important OTA parameters are ...
