Abstract
A disclosed linearization circuit includes a reference component, a charging and discharging controller, and a comparator circuit. The reference component has a non-linear dependence on current or voltage. The charging and discharging controller is configured to control alternating charging and discharging of the reference component. A voltage associated with the reference component forms a reference signal. The charging and discharging are controlled such that the reference signal has a periodic time dependence. The reference signal and a measurement signal are received by the comparator circuit. The comparator circuit is configured to generate and output a square-wave signal based on a reference time point during a charge-discharge cycle, and based on a result of a comparison of the reference signal with the measurement signal, such that the square-wave signal represents a linearized output signal. This disclosure further relates to a corresponding method.
