Latest Patents
Junkai Chen holds a patent for a capacitance measurement circuit. This circuit includes an analog front-end (AFE) circuit with current mirror circuits, a parasitic capacitor, an AD converter, an output shift register, and a controller. The controller plays a crucial role in disconnecting the capacitor to be measured and connecting one current mirror circuit to record an AFE output voltage Vcollected at the inverting input terminal of the AD converter. It then connects the capacitor to be measured to collect an AFE output voltage Vat at the non-inverting input terminal of the AD converter. The circuit converts the value of (V−V) into a first digital signal and determines, based on this value, a connection number m of the current mirror circuits. The analog front-end circuit is controlled to connect m current mirror circuits, and the steps are repeated to obtain a second digital signal. Finally, the second digital signal is shifted based on the connection number m to obtain a capacitance measurement value. This innovative approach enhances the accuracy and efficiency of capacitance measurements.
