  • RECEIVER COMPRISING TWO TUNNERS
    Publication number: 20090027145
    Abstract: A receiver comprises two tuners and a DC-to-DC converter (DCC) for generating an increased supply voltage (VH) on the basis of a main supply voltage. Each tuner comprises a tunable circuit (TUC1), which can be tuned by means of a tuning voltage (VT1). Each tuner further comprises a tuning control circuit (TCC1) that is coupled to the DC-to-DC converter (DCC) via a load circuit (LD1) for generating the tuning voltage (VT1). The load circuit (LD1) of at least one of the two tuners comprises a branch (D1) coupled to receive the main supply voltage (VCC). The branch (D1) is conductive when the tuning voltage (VT1) is within a voltage range substantially comprised between 0 and the main supply voltage (VCC).
