Explanation: A photovoltaic cell is semiconductor junction device that convert radiation energy into electrical energy and hence it does not require external voltage. 6. If the input applied to DAC using current to voltage converter is 10110100, determine the reference voltage (Assume Io= 2mA and R1=1.2kΩ)
