How to use BJT Bipolar Junction Transistor – Beginner’s Tutorial

WebMOSFETs are too noisy for many precision amplifier applications. If you have a low impedance source, for the lowest noise of any available monolithic amplifier, you need to go to a bipolar amplifier such as the LT1028 which has a white noise spectral density of 1.1nV/sqrt(Hz). (If that's not good enough, a discrete design can do better). WebFor 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). ...

Often this type of ADC is used as a first medium-sized analog circuit verification. The earliest implementations consisted of a reference ladder of well matched …

WebA converter that is used to change the analog signal to digital is known as an analog to digital converter or ADC converter. This converter is one kind of integrated circuit or IC that converts the signal directly from continuous form to discrete form. This converter can be expressed in A/D, ADC, A to D. WebBJT can handle a lot more current than MOSFETs. One of the reason why they are still in use is BiCMOS applications where basically CMOS part is used as the logic and BJTs are used to drive very high capacitance nodes. Other than that, they have very nice properties regarding their PN junction nature.
