Autoadjustment of RC cells in a circuit
The circuit has a DC/DC converter to transfer battery voltage to regulated supply voltage. The converter has a ramp generator (13) including a calibrating circuit (106) for producing an adjustment value for an adjustable resistor (R) of a pair of components in order to compensate error on resistor a...

| Zusammenfassung: | The circuit has a DC/DC converter to transfer battery voltage to regulated supply voltage. The converter has a ramp generator (13) including a calibrating circuit (106) for producing an adjustment value for an adjustable resistor (R) of a pair of components in order to compensate error on resistor and capacitor product of the pair. The adjustment value is then applied to an adjustable capacitor of another pair of components. An independent claim is also included for a method of calibrating pairs of components. |
