Input Offset Voltage Null Circuit

This circuit is application of OP07. adjust variable resistor for null Offset
Voltage output at initrial state

Op07 represent a breakthrough in operational amplifier performance.
Low offset and long-term stability are achieved by means of a low-noise,

chopperless, bipolar-input-transistor amplifier circuit. For most applications,

external components are not required for offset nulling and
frequency compensation. The true differential input, with a wide input
voltage range and outstanding common-mode rejection, provides
maximum flexibility and performance in high-noise environments and in

noninverting applications. Low bias currents and extremely high input
impedances are maintained over the entire temperature range.
The OP07 is unsurpassed for low-noise, high-accuracy amplification of
very low-level signals.
