Abstract
A circuit includes a digital-to-analog converter and a gain stage. The gain stage includes: an operational amplifier; a variable gain network; and a leakage current control circuit. A first input of the operational amplifier is coupled to an input of the gain stage. An output of the operational amplifier is coupled to an output of the gain stage. A first terminal of the variable gain network is coupled to the second input of the operational amplifier. A second terminal of the variable gain network is coupled to the output of the operational amplifier. A first terminal of the leakage current control circuit is coupled to the output of the operational amplifier. A second terminal of the leakage current control circuit coupled to a third terminal of the variable gain network.
