5 Global Biasing

5.1 Biasing Overview

RFSYS有一個全域性帶隙引用，用於生成各種不同的當前引用，然後分發到不同的子系統。

提供了四種型別的偏置。

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的每個功率子域都是由一個低損耗調節器來調節，以進行正確的電源調節。這些都是針對每一項要求定製的，例如噪音、反向隔離(高fre)。(漏電)，直流精度，直流負載要求，PSSR等。總體電力計劃如圖5所示
