A current-to-voltage conversion circuit according to one aspect of the present invention includes a first resistor, a first current source, a first capacitor, a first output terminal, a first voltage source, a
One example of such an application is using the photodiode sensor to measure light intensity. The output of the photodiode sensor is a current which changes proportional to the light intensity. Another advantage of the opamp circuit is that the voltage across the photodiode (current source) is...
Current to Voltage Source Transformation: In contrast to the above conversion, if we have a current source (on the right side), we can transform it into a voltage source (on the left side) using the following formula. The above process can be reversed, if we have a current source (on ...

constraints are that scale factors must be chosen to minimize errors due to bias current and since voltage gain and source impedance are often indeterminate (as with photocells) the amplifier must be compensated for unity-gain operation. Valuable techniques for bias current compensation are contained...
A conversion circuit includes a super source follower circuit configured to lower an impedance of a first node. A digital control circuit is configured to adjust a current at the first node based on a current through the super source follower. An output transistor has a gate configured to recei...
