Abstract:
Circuits and methods for eliminating or mitigating the amount of temperature-dependent variation in the relative attenuation of a multi-valued digital step attenuator (DSA) by using resistive components having temperature-dependent resistance values that compensate for or offset changes in the temperature-dependent ON resistance (R ON ) of the switches within the DSA. In some embodiments, DSA attenuator cell switches are fabricated to have positive first-order resistance temperature (FORT) coefficients, while temperature-compensating series attenuation resistances are fabricated as a positive FORT coefficient resistor and temperature-compensating shunt resistances are fabricated as either a negative FORT coefficient resistor or a combination of a negative FORT coefficient resistor in parallel with a positive FORT coefficient resistor.

Claim (Index 1):
A temperature-compensated attenuator cell, including:\n (a) a switch having a first-order resistance temperature coefficient of a first type; and (b) a resistance element corresponding to the switch, the element coupled to the corresponding switch and having a first-order resistance temperature coefficient of a compensating type with respect to the coupled corresponding switch.
