Question
### Understanding Transistors in Current Mirrors **2.4. Current Mirror Saturation in PMOS and NMOS Transistors** To be used effectively as a current mirror, transistors should be in saturation. However, being in saturation does not inherently mean they function as a current mirror. We'll explore this concept with PMOS and NMOS gate-drain connected transistors. #### Transistor Diagrams - **(a) PMOS Transistor:** - **VDD**: The positive supply voltage. - **S**: Source terminal, connected to the current source. - **G**: Gate terminal, linked directly to the base. - **B**: Base terminal, connected to the gate. - **D**: Drain terminal, connected internally to the gate. - **(b) NMOS Transistor:** - **D**: Drain terminal, connected internally to the gate. - **G**: Gate terminal, linked directly to the drain. - **S**: Source terminal, connected to the current source. - **B**: Base terminal, tied to the source. ### Explanation When transistors are in saturation, they have the potential to operate as a current mirror by copying current from one branch to another. However, merely being in saturation is not sufficient—proper configuration and connections are necessary to ensure accuracy and functionality as a current mirror. This involves careful management of gate-to-source voltage and the maintenance of minimal channel-length modulation effects. Understanding these schematic configurations allows for the exploration of nuances in transistor behavior essential for advanced electronic circuit design.
