In this paper a new analog-to-digital converter (ADC) architecture for the conversion of currents down to the subpicoampere range is presented. A single transistor stage is used to integrate and amplify the input current resulting in simple and area-effective designs. Although the transfer function of the transistor is not linear, inherent linearity of the conversion is achieved by a constant transistor voltage swing and correlated double sampling. The circuit is well suited for highly… CONTINUE READING
