基于一款LED驱动芯片中耗尽型高压NLDMOS器件的参数要求,提出一种耗尽型高压NLDMOS的器件结构和参数设计优化方法。
Analyzing the parameters of the depletion-mode HV-NLDMOS used in a LED driver IC, the structure of DM-NLDMOS and optimal design method of its parameters were proposed.
该电路采用耗尽型NMOS管作电流源器件,结合负反馈,实现了稳定的电压基准。
A depleted NMOS transistor, which was used as current source, and a negative feedback loop constitute a stable voltage reference.
这种算法对增强(e -)和耗尽(D -)型MOS器件都适用,且避免了对泊松方程的严格数值求解。
The algorithm applies to both enhancement (e -) and depletion (d -) MOS and the strict solution of Poisson's equation by numerical method is avoided.
