Abstract
A current to voltage amplifier in accordance with the present invention includes a current to voltage amplifier for receiving a sensor input to thereby output an amplified voltage corresponding to the sensor input including a bias current provider for providing a bias current, an input block for flowing a sensor current based on the sensor input, a first diode-connected MOS transistor for receiving the bias current from the bias current provider and providing the sensor current to the input block, and a first MOS transistor for flowing a remnant current subtracting the sensor current from the bias current, wherein the amplified voltage is corresponded to the current.
