WebJun 1, 2024 · In MOSFET, either electrons or holes act as charge carriers depending on the type of channel between source and drain. Polarity. BJT is a bipolar device. MOSFET is a unipolar device. Controlling quantity. BJT is a current controlled device. MOSFET is a voltage controlled device. Input impedance. BJT has low input impedance. WebMOSFETs have a very high input impedance in the megohms region, whereas BJTs have a kiloohms input impedance. As a result, MOSFET manufacturing is appropriate for amplifier-based circuits. MOSFETs produce less noise when compared to BJTs. The random intrusion within a signal is referred to as noise here.

WebBJTs offer greater gain at the output than FETs. The gain (or transconductance) of FETs are smaller than for BJTs. Size: BJTs are larger in size and therefore take up more physical space than FETs normally. FETs can be manufactured much smaller than BJTs. This is especially important for integrated circuits that are composed up of many transistors. Web1. Bipolar junction transistors (BJTs).

In the following discussion we will try to understand why MOSFETs work better in power amplifier designs, compared to BJTs. …

WebA BJT has three elements: an emitter, collector, and base, whereas a MOSFET has three elements: a gate, source, and drain. BJTs are used in low-current applications, whereas MOSFETs are used in high-power applications. MOSFETs are now believed to be more widespread than BJTs in digital and analog circuits. WebApr 20, 2004 · Short answer: Class B: For low to medium power output (<100 watt RMS), BJTs are the best tradeoff for most applications. For higher output, use MOSFETs -- primarily because they will have higher reliability at high power outputs. MOSFETS will cost more, and require a more complex circuit with more front end gain to achieve similar …

WebAug 12, 2024 · Whichever is lower depends on the specific parts and the current. Generally, for transistors rated up to only a few 100 V, MOSFETS will dissipate less. However, the R dson gets worse with voltage capability, so above a few 100 V, BJTs usually win. BJTs are also controlled by current, while MOSFETS by voltage. WebJun 21, 2024 · Unlike bipolar junction transistors (BJTs), JFET uses the voltage applied to the gate terminal to control the current flowing through the channel between the drain and source terminals which results in output …

WebMay 6, 2024 · Compare: 12V circuit, with 500mA being switched on/off. BJT will have ~0.7V drop from Collector to Emitter, rest of circuit has 11.3V drop across it. MOSFET will have say 50mOhm on-resistance. With 500mA, V=IR so voltage drop is 0.025V. More voltage available for your load - say a motor, or strings of LEDs. ... BJTs conduct in more ways …
