Analog OR circuit with wide input voltage detection range |
摘要 |
An analog OR circuit selects from a plurality of input voltages to supply other circuits within a device, especially battery powered devices, such as portable telecommunications devices. A plurality of input circuits convert the input voltages to current signals which are averaged to generate a reference current signal. A comparison is made between the input current signals and the reference current signal to generate comparison signals which are output to a winner-takes-all circuit or a comparator for selecting the strongest input voltage signal.
