Silverlining said:A CMOS inverter is built using a PMOS transistor with KP = - 0.5 mA/V2 and KN = 1.2 mA/V2. If VDD = 5V, VTN = 1.0V, and VTP = - 1.2V, find the input cross-over voltage VIC.
Silverlining said:If i knew which formulas to use i could easily do this... the rest is simply kvl and kcl
A CMOS (Complementary Metal-Oxide-Semiconductor) inverter is a type of logic gate that uses complementary pairs of p-type and n-type MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) to implement logic functions. It is a fundamental building block in digital integrated circuits.
VIC (Voltage-Input Characteristics) refers to the relationship between the input voltage and output voltage of a CMOS inverter. It is commonly used to analyze the performance and behavior of a CMOS inverter.
KP and KN are the process transconductance parameters for the p-type and n-type MOSFETs, respectively. They are related to the mobility and channel width of the MOSFETs. VDD is the supply voltage for the CMOS inverter.
KP and KN affect the speed, power consumption, and noise margin of a CMOS inverter. A higher value of KP (or a lower value of KN) will result in a faster inverter, but also consume more power and have a lower noise margin. It is important to balance these parameters for optimal performance.
VDD determines the voltage range in which the CMOS inverter can operate. A higher VDD will result in a larger output voltage swing and faster switching speed, but also consume more power. A lower VDD will have the opposite effect. The choice of VDD depends on the specific application and design considerations.
