J'ai postulé via un recruteur. J'ai passé un entretien chez Defibtech (Guilford, CT) en nov. 2020
Entretien
internal recruiter sent me an email with job description. I expressed interest and she arranged Zoom interviews. There were 3 zoom meetings totaling about 4 hours.
Mostly conversation style, some circuit questions.
Questions d'entretien [3]
Question 1
Npn bias: base connected to mid point of 3k-7k divider with terminals at 0V and 10V. Emitter has 2kohm to gnd.
Collector has 2kohm to 10V. What is the voltage at base, emitter, collector
opamp with resistors forming an inverting amplifier, gain -2. Non inv input at gnd = 0V
There is additional resistor (R3) from inverting input to gnd.
what is the voltage gain
