Latest Patents
Yongnan 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 at the inverting input terminal of the AD converter. It then connects the capacitor to be measured to collect an AFE output voltage at the non-inverting input terminal of the AD converter. The circuit converts the value of the difference between these voltages into a first digital signal. Based on this signal, the controller determines the connection number of the current mirror circuits, controls the AFE circuit to connect the appropriate number of circuits, and repeats the process to obtain a second digital signal. Finally, it shifts the second digital signal based on the connection number to obtain a capacitance measurement value. Yongnan Chen has 1 patent to his name.
