Analog to digital converter with offset error correction |
摘要 |
An analog to digital converter of the ramp-integrator type with provisions to reduce errors due to offset voltages. The cycle which is utilized includes a preconditioning cycle during which the capacitor is charged while the input to the buffer amplifier is connected to the datum level voltage, such as ground. A microprocessor is used to compute the unknown signal.
