Temperature compensation attenuator |
摘要 |
In one embodiment, a temperature compensating attenuator is disclosed having an attenuation circuit and a control circuit. The temperature compensating attenuator circuit may include a first series connected attenuation circuit segment and a shunt connected attenuation circuit segment, as well as additional attenuation circuit segments. Each attenuation circuit segment includes a stack of transistors that are coupled to provide the attenuation circuit segment with an impedance attenuation level having a continuous impedance range. The control circuit may be operably associated with the stack of transistors in each attenuation circuit segment to control the attenuation level of the attenuation circuit. The temperature compensating attenuator includes a temperature compensating circuit that compensates for variations in operation of the attenuation circuit due to a temperature change.
