摘要
Abstract
Owing to the continual enhancement of conversion accuracy and speed of phase digitizing DAC, higher performance current source is demanded.A circuit structure of current source is introduced,the merits and shortcomings are analyzed,and a method for layout design of reducing the process variation and device mismatch is adopted.The simulation is performed based on 90 nm CMOS process,and the results show that this structure has high output impedance and accuracy at 2 GHz clock rate.关键词
