Process and temperature-independent voltage controlled attenuator and method |
| abstract |
A circuit includes a first variable resistor having a resistance which is variable in response to a resistance control signal. A resistance control circuit includes a first current source circuit for supplying a first current through a reference resistor. A second current source circuit supplies a second current through the first variable resistor. In operational amplifier has a first input coupled to a first conductor connecting the first current source to the reference resistor, a second input coupled to a second conductor connecting the current source to the first variable resistor, and an output applying the first resistance control signal to a control terminal of the first variable resistor, to force the resistance of the first variable resistor to be equal to a resistance of the reference resistor. The resistance of a second variable resistor of an attenuator is controlled in response to the resistance control signal. |
