Abstract
An integrated circuit (IC) includes an analog-to-digital converter (ADC). The ADC includes an ADC core circuit integrated in the IC to receive an analog signal, to convert the analog signal to a digital signal in response to a trigger signal. The ADC core circuit further provide the digital signal as an output of the ADC. The ADC further includes internal trigger circuitry integrated in the ADC to provide the trigger signal to the ADC after a prescribed delay period has expired.
Claims21
1-20. (canceled)
An integrated circuit (IC), comprising:
- an analog-to-digital converter (ADC), comprising:
- an ADC core circuit integrated in the IC to receive an analog signal on an input channel of the ADC and to convert the analog signal to a digital signal in response to a trigger signal;
- and
- internal trigger circuitry integrated in the ADC to provide the trigger signal to the ADC after a prescribed delay period has expired, wherein before expiration of the delay period the ADC core circuit performs a scan sequence conversion.
The integrated circuit (IC) according to claim 72, wherein the prescribed delay periods are equal.
A microcontroller unit (MCU) included in an integrated circuit (IC), the MCU comprising:
- an analog-to-digital converter (ADC), comprising:
- an ADC core circuit integrated in the IC to convert an analog signal to a digital signal in response to a trigger signal;
- and
- internal trigger circuitry integrated in the ADC to provide the trigger signal to the ADC after a prescribed delay period has expired, wherein the ADC core circuit is turned off until the prescribed delay period expires.
A method of performing signal conversion in an integrated circuit (IC), the method comprising:
- receiving an analog signal in an analog-to-digital converter (ADC) integrated in the IC;
- generating a trigger signal, using internal trigger circuitry integrated in the ADC, after a prescribed delay period has expired;
- converting, in response to the trigger signal, the analog signal to a digital signal by using the ADC;
- and
- performing a scan sequence conversion before the prescribed delay period has expired.
