Abstract: A boost-type converter circuit includes a pair of converter switches that are alternatively switchable on and off. An inductor is coupled to the intermediate point between the converter switches. A driver module controls switching on and off of the converter switches in respond to a comparator output signal. A reference signal line provides to the comparator a reference signal, and an output feedback line provides to the comparator an output feedback signal. These signals are compared to each other to generate the comparator output signal for controlling the driver module. A low-pass filter network is coupled to the inductor and configured to provide a ripple current which is a low-pass filtered replica of the current through the inductor. An injector circuit injects the ripple current into the reference signal line coupled to the comparator.

Abstract: A solid state sensor to sense pressure includes a semiconductor substrate having a crystallographic design axis, and an odd number of identical inverter modules coupled in series to form a ring oscillator on the semiconductor substrate. Each inverter module includes a pair of structurally identical CMOS inverter stages. A logic input circuit starts oscillation of the ring oscillator and select a signal propagation path therein, either through CMOS inverter stage more affected by the induced mechanical stress or through CMOS inverter stages less affected by the pressure, using two logic command signals. The ring oscillator allows a reading of a frequency of oscillation based on the two logic command signals.
