Abstract:
1. A temperature compensating attenuator, comprising: a first attenuation circuit having a first attenuation level, the first attenuation circuit comprising: a control circuit adapted to receive an attenuation control signal, the control circuit being coupled to the first plurality of stacked transistors and the second plurality of stacked transistors to control the first attenuation level of the first attenuation circuit based on a signal level of the attenuation control signal; and a temperature compensating circuit being operable to generate an attenuation control adjustment signal having a signal level related to a temperature change in an operating temperature associated with the first attenuation circuit, the temperature compensating circuit being operably associated with the control circuit so that the attenuation control signal is adjustable based on the signal level of the attenuation control adjustment signal.
