WebThis process can take a long time. For example, an amplifier with a field-effect-transistor (FET) input, having a 1-pA bias current, coupled via a 0.1-μF capacitor, will have a charging rate, I/C, of 10 –12 /10 –7 = 10 μV/s, or 600 μV per minute. If the gain is 100, the output will drift at 0.06 V per minute. WebOct 12, 2013 · BJT (bipolar junction transistor) are widely used an amplifier, oscillator, switch etc. It is a current-driven device ( MOSFET is voltage driven), the output current is equal to the input current times a factor which is called Gain. A basic BJT has three pins: the Base, Collector, and Emitter.
WebThe BJT is a three terminal device and it comes in two different types. The npn BJT and the pnp BJT. The BJT symbols and their corresponding block diagrams are shown on Figure 1. The BJT is fabricated with three separately doped regions. The npn device has one p region between two n regions and the pnp device has one n region between two p regions. WebBipolar junction transistors (Also known as BJTs) can be used as an amplifier, filter, rectifier, oscillator, or even a switch, which we cover as an example in the first section. The transistor will operate as an amplifier or …

WebJul 6, 2014 · Saturation in transistors (BJTs) - why and how. When a bipolar junction transistor (BJT) is used to switch a load (e.g. a relay, an LED, a buzzer, a small motor, etc) ON and OFF, it is most often operated as a "saturated switch". This article explains saturation in BJTs - why it is used, and how to calculate the base resistor to ensure …
Weba ADC implemented entirely in discrete components (2N3904, 2N3906, Resistors, Capacitors), without the use of MOS components anywhere in the modulator portion of the system. Ultimately, a ADC was built with a 1-bit sampling rate of approximately 500 Hz, with maximum func-tional bit-depth of 9-bits. The ADC was implemented in conjunction with mike smith network railWebFor example, a 20-bit ADC can be made to act as a 24-bit ADC with 256× oversampling. The over-sampling technique is typically used in audio frequency ADCs where the required sampling rate (typically 44.1kHz) is very low compared to the clock speed of typical logic circuits (>1MHz). ...
