Voltage peak measurement with digital memory |
摘要 |
A technique for measuring peak voltages is provided that may be used in RF transceivers or receivers of wireless local area network systems. In an apparatus for measuring a peak value of an analog voltage, an analog to digital converter is connected to receive an input voltage. A voltage level detection unit detects a voltage level of a received input voltage, and a digital memory receives and stores the detected voltage level. The digital memory updates the stored voltage level only if the currently detected voltage level is higher, or lower, than the stored level. A digital code is output that corresponds to the stored voltage level. The provided technique may allow for a more simple and less complex implementation.
