本文设计了一种单恒流源电流频率转换电路,使电路的功耗减小一半,更加小型化,并且具有更好的对称性和精度。提出并从原理上论证了这种单恒流源I/F技术的理论依据,设计出相应的硬件电路,验证其原理的正确性和工程上的可行性。为单恒流源I/F技术的研发,拓展了思路,奠定了基础。 This paper designed a single constant current source current frequency conversion circuit, the circuit power consumption reduced by half, more miniaturization, and has better symmetry and accuracy. Proposed and theoretically demonstrated the theoretical basis of this single constant current source I / F technology, designed the corresponding hardware circuit, verify the correctness of the principle and the feasibility of the project. As a single constant current source I / F technology research and development, to expand ideas, laid the foundation.
