5 Global Biasing

5.1 Biasing Overview

RFSYS有一个全局带隙引用，用于生成各种不同的当前引用，然后分发到不同的子系统。

提供了四种类型的偏置。

1. VBG/RI : temperature compensated current referred to an on-chip poly-p+ resistor (RI)

2. VPTAT/RI : PTAT current referred to an on-chip poly-p+ resistor (RI)

3. VBG/RT : temperature compensated current calibrated to an external resistor (RT) 

4. VPTAT/RT : PTAT current calibrated to an external resistor (RT)

6 LDO’s and Level Shift Biasing

RFSYS的每个功率子域都是由一个低损耗调节器来调节，以进行正确的电源调节。这些都是针对每一项要求定制的，例如噪音、反向隔离(高fre)。(漏电)，直流精度，直流负载要求，PSSR等。总体电力计划如图5所示
