That means Vsd should be greater than or equal to Vsg - |Vt| • At 11:11, Instead of Vt in the equation, it should be |Vt| for PMOS transistor. • What is Active Load? • In MOSFET amplifier circuits, instead of a passive resistor, the active component like a MOSFET or MOSFET circuit (Current Mirror) is used to increase the gain of the amplifier. This active component or the active circuit is known as the Active Load. • Why Active Load is used in circuit design? • The Active Load is usually used in the integrated circuits where the size and power consumption are major constrain. Also, in the integrated circuits, fabricating a resistor requires a lot of space. And therefore, instead of a resistor, the active load is used. The active load also helps in increasing the voltage gain of the amplifier. • The link for the other useful videos related to MOSFET: • 1) MOSFET Biasing: Enhancement Type MOSFET Biasing Explained • • MOSFET Biasing : Enhancement Type MOS... • 2) MOSFET Channel Length Modulation • • MOSFET- Channel Length Modulation Exp... • 3) MOSFET Small Signal Model: • • MOSFET Transconductance and MOSFET Sm... • 4) MOSFET Common Source Amplifier (Voltage Divider Bias) • • MOSFET Common Source Amplifier - Smal... • 5) MOSFET Common Gate Amplifier • • MOSFET Common Gate Amplifier (Small S... • This video is helpful to all the students of science and engineering for understanding what is active load and the importance of active load in amplifier circuits. • #ALLABOUTELECTRONICS • #MOSFET • #ActiveLoad • #MOSFETAmplifier • #MOSAmplifier • -------------------------------------------------------------------------------------------------- • Follow my second channel: • / @allaboutelectronics-quiz • Follow me on Facebook: • / allaboutelecronics • Follow me on Instagram: • / all_about.electronics • -------------------------------------------------------------------------------------------------- • Music Credit: http://www.bensound.com
