Tuners inventions 01/09

20090027145 - receiver comprising two tunners: 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... Agent: Nxp, B.v.

20090021332 - Array of capacitors switched by mos transistors: An integrated variable capacitance with low losses comprises an array (1) of switched capacitors (2-8). When using an array (1) of switched capacitors (2-8) to form a quasi continuously variable capacitor, a continuity of capacitance as function of the digital control signal to the array (1) leads to overall behavior...
