ABSTRACT:
A current-input, autoscaling, dual-slope A/D converter includes means for adjusting the integration period of the input current to effectively adjust a scale factor associated with the converter. An integrator circuit of the converter includes means for precharging an integration capacitor of the integrator circuit to an off-set voltage associated with an amplifier of the integrator circuit, so as to effectively eliminate integration error due to the off-set voltage. A PMOS switching transistor associated with precharging the integration capacitor is formed in an n-well biased to a voltage approximately equal in magnitude to a voltage held across the integration capacitor, so as to minimized leakage current from the capacitor through the PMOS switching transistor.
