It is OK to apply a voltage higher than 6.4 V to the B terminal. Increasing the input voltage only brings the BRT into deeper saturation (i.e., decreases VCE(sat)). This causes the base-...
It is generally inadvisable to calculate errors over unspecified temperature ranges unless the temperature drift characteristics are well understood.Long Term StabilityThis is a measure of the tendency of a reference voltage to change over time, independent of other variables. Initial shifts are largely...
To calculate the parameters safely we must take care of the following considerations: Current Sharing with Emitter Resistors: The voltage drop across each emitter resistor is supposed to be approximately equal. The value of the emitter resistors can be calculated with regards to the desired current ...
This electronics video tutorial provides a basic introduction into the common emitter amplifier which uses a NPN bipolar junction transistor. This video explains how to calculate the voltage gain, current gain, and power gain of the CE amplifier circuit. Got Questions ! Your Answers> What is the ...
Note the equation at the bottom of the diagram above: The formula to calculate the voltage out of a voltage divider is:Voltage Out = Voltage In * resistance below the output / total resistanceWe can calculate the voltage out of the voltage divider by multiplying the Voltage in * R2 / (...
To calculate the boost converter’s power stage, the following guidelines are necessary: Input Voltage Range: Vin(min) and Vin(max) Minimum Output Voltage: Vout Maximum Output Current: Iout(max) IC specifications: Choose based on the IC’s datasheet. ...
• The adjustment range of the VCOM voltage is thus from V(AVDD)/4 to V(AVDD)/2. Capacitor C1 makes a low-pass filter with the output resistance of the level shifter. The minimum output resistance of the level shifter is 50 kΩ, and this value must be used to calculate the filter...
CTR = -I-C-- IF x 100 % (1) There are typically a number of CTR groups (binning) to choose from when selecting an optocoupler. CTR is not a static value. It is affected by the forward current (IF), the collector-emitter voltage (VCE), and the ambient temperature (Tamb). The ...
We recommend a value of 10k, but any value from 1k to 100k would be acceptable. Now that the desired collector current has been found, you can calculate the final component value. RC is calculated using Kirchhoff's voltage law, drawing a loop through the base-emitter junction of the ...
These factors cause a change in the phototransistor's collector-emitter voltage (VCE), which leads to an increase or decrease in the input current of the power supply, and consequently an increase or decrease in the power supply's output voltage. ...
