MICROCONTROLLER ADC BASED ON THE TRANSIENT IN THE RC CIRCUIT Russian patent published in 2022 - IPC H03M1/38 G01R27/26 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology, in particular to analogue-to-digital converters, and can be used in digital systems for measuring analogue values. The microcontroller ADC based on the transient process in the RC circuit contains a microcontroller 1, a reference voltage source (RVS) 2, a first resistor 3, a capacitor 4 and a second resistor 5. Resistor 3 and capacitor 4 are connected by their first pins to the first input of an analogue comparator built into the microcontroller 1. ION output is connected to the second output of resistor 3. The second output of capacitor 4 is connected to the first output of resistor 5 and to the digital output of microcontroller 1. The second output of resistor 5 is connected to the common power bus. The second input of the analogue comparator of the microcontroller 1 is connected to the second output of the analogue signal source, the first output of which is connected to a common power bus.

EFFECT: improving the accuracy of analogue-to-digital conversion.
