The proposed topology has been designed in order to operate at a reduced supply voltage (the minimum being 1.2 V) with low power consumption. A 1.4-V design with an overall power consumption of only 23 [mu]W is presented. A five decades capacitive range (10 fF-100 pF), to which corresponds a frequency span of about 300 Hz-3 MHz, has been considered. The circuit shows low noise, low sensitivity to supply voltage variations and good output linearity. These characteristics have been verified to be fully satisfactory if compared to corresponding performance of two other typical solutions presented in literature.

The dynamics of the converter is analyzed in detail, showing the importance of properly accounting for the nonlinearity in the optimization process. A procedure to determine a set of optimization parameters is finally presented.
