摘要： A digital voltmeter, where a number of clock pulses for a first ramp voltage to reach an input voltage is determined. Next, a number of clock pulses for a second ramp voltage to reach the input voltage is determined. One of the first and the second ramp voltages having a least number of clock pulses to reach the input voltage is determined. A determination is made for a number of clock pulses for the determined one of the first and the second ramp voltages to reach a reference voltage. A digital code is generated for the input voltage based on the determined number of clock pulses for reaching the reference voltage and the determined least number of clock pulses for reaching the input voltage.

摘要： An analog signal measuring device for measuring an analog signal includes a digital controller, a waveform converter and a comparator. The digital controller includes a PWM controller for outputting a pulse signal having an adjustable pulse width to the waveform converter, which converts the pulse signal into a sawtooth wave or a triangle wave for output as a carrier signal. Next, the comparator feeds a comparison pulse signal, which is obtained by comparing the carrier signal to the analog signal, to the digital controller, which enables or disables the counter to generate a count value corresponding to the comparison pulse signal. Since the count value depends on the comparison pulse signal and the type of the comparison pulse signal is directly related to the analog signal, the digital controller may get the analog signal according to the count value.

摘要： A method for determining a power source voltage level of a power source in a system in which the power source is connected to a microcontroller. A charging circuit is in direct communication with a pin of the microcontroller and the power source voltage level is determined by charging the charging circuit using a constant voltage level and determining a time when the charging circuit attains a voltage level sufficient to transition the pin of the microcontroller from a state corresponding to a logic “0” to a state corresponding to a logic “1.” The determined time and a predetermined relationship between the power source voltage level and an input port transition voltage value of the microcontroller is then used to determine the power source voltage level of the power source.
