Abstract
A nonvolatile analog memory has a floating gate point. The nonvolatile analog memory includes a capacitor, a first current source, a second current source and a current adjuster. The first current source controlled by a voltage value at the floating gate point and generates a first current. The second current source controlled by the voltage value at the floating gate point and generates a second current. The current adjuster receives the output voltage and a reference voltage and adjusts the first current and the second current based on the output voltage and the reference voltage. The current adjuster charges or discharges the capacitor to equalize the output voltage to the reference voltage.
