NMOS和PMOS在LDO的应用原理

一般工作线上性区域的电晶体，可以把它当作是一个压控电流源，去控制电路并连续检测输出电压，然后根据负载的需求，进行调节电流源，确保输出电压能够保持在期望的数值。 电流源的设计极限就出现了作用：它限定了稳压器在保持电压调节作用的情况下 ...

Use Hybrid PMOS-NMOS Active Loads To Cut Substrate Noise In Differential Amplifiers

PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...
