What is the threshold voltage of silicon and germanium?
In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.
Difference between Threshold voltage and knee voltage?
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
What is lower threshold voltage?
the voltage above which any device starts conducting
What is knee voltage for GAAs?
Knee voltage, also known as threshold voltage, in Gallium Arsenide (GaAs) refers to the minimum voltage required to initiate significant current flow in a GaAs device, such as a transistor or diode. This voltage is crucial for determining the operational characteristics of GaAs-based electronic components. Typically, knee voltage in GaAs devices is lower compared to silicon counterparts, making GaAs favorable for high-frequency and high-efficiency applications.
What is the threshold voltage of silicon and germanium?
In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.
What is the cut in voltage of germanium and silicon diodes?
cut in voltage *** for silicon is 0.7volts and that for germanium is 0.3volts.According to Millman and Taub, "Pulse, Digital and Switching Waveforms", McGraw-Hill 1965, the cutin (or offset, break-point or threshold) voltage for a silicon diode is 0.6, and 0.2 for germanium.Breakdown voltage is another thing entirely. It is the reverse voltage at which the junction will break down.
What is the lowest stimulus voltage that induces active force in the skeletal muscle?

Why is a Schmitt trigger called a regenerative comparator?
A Schmitt Trigger is a comparator, because it compares its input voltage to a "threshold" voltage, but it has _two_ threshold voltages (the upper and lower trigger voltages), and which threshold voltage is used depends on the output state. If the input voltage is higher than the upper trigger voltage, the output will be high (for a non-inverting Schmitt trigger). In this state, the input is compared to the lower threshold voltage, so the input now has to go below the lower threshold voltage before the output will go low. The threshold voltage depends on the output state, such that a high output selects the lower threshold voltage, and a low output selects the upper threshold voltage. This can be visualised as using a fixed threshold but adding a small voltage (the difference between the upper and lower threshold voltages, also called the hysteresis voltage) to the input voltage before it is compared. This small added voltage is high when the output is high, and low when the output is low. A small amount of the output voltage is effectively being added to the input voltage before it is compared to a fixed threshold. This is positive feedback, also called regenerative feedback. So a Schmitt trigger operates as a voltage comparator, and a small amount of the output is added to the input, so it uses positive or regenerative feedback.
Why polysilicon is used as gate in mos technology?
Because of threshold voltage reduction of MOSFETs. Comparing with metals for the gate of MOSFETs, polysilicon has small work function difference with the substrate silicon of MOSFETs.
What is knee voltage for silicon and germanium?
The knee voltage for silicon is approximately 0.7V, while for germanium it is around 0.3V. The knee voltage is the voltage at which a diode starts conducting significantly.
What is the voltage threshold for GAAs?
1.7 volts
