Answer:A
Which of the following can be used in series with a Zener diode so that combination has almost zero temperature coefficient?
A. Diode B. Resistor C. Transistor D. MOSFET
Explanation: If a Zener diode of TC of about -2mV is connected with a forward diode (which has a TC of about +2mV) in series, the combination can be used to obtain a very low (close to zero) TC.
