1. What are BJT arrays used for?
BJT arrays are often used in analog circuits like amplifiers, switches, and oscillators where matched transistor pairs are required for balanced performance.
-
2. What advantages do BJT arrays offer over single transistors?
BJT arrays provide better matching between transistors, reduce PCB space, and improve thermal performance since all transistors share the same substrate.
-
3. How does the thermal coupling affect BJT arrays?
Thermal coupling ensures uniform behavior across transistors in the array, improving performance in applications like differential amplifiers.
-
4. What are the limitations of BJT arrays?
While they save space, they can limit flexibility if specific transistor types or configurations are needed. Also, thermal coupling might not always be beneficial in all scenarios.
