A. Pinched resistor B. Epitaxial resistor C. Thin film resistor D. All of the mentioned
Explanation: In a pinched resistor, the sheet resistivity can be increased by reducing its effective area. This technique is used to achieve high value of sheet resistance from ordinary diffused resistor. 3. How pinched resistor can give resistance in order of mega-ohm in a reasonably small area?
