摘要： An input resonance circuit of a tuner is provided to improve receive sensitivity of the first band(UHF(UltraHigh Frequency)) in selecting UHF. A UHF input resonance circuit(31) inputs/tunes the first band(UHF) from an RF(Radio Frequency) signal received through an HPF(High Pass Filter) from an antenna(ANT). An IF(Intermediate Frequency) trap unit(30) removes only an IF signal from the RF signal received through the HPF from the antenna(ANT). High and low VHF input resonance circuits(32,33) input/tune the second band(VHF(Very High Frequency)) from the RF signal outputted from the IF trap unit(30). A switching circuit(34) lowers an output level of the second band outputted when the first band is selected at the IF trap unit(30). The switching circuit(34) is provided between the IF trap unit(30) and the VHF input resonance circuit(32).

摘要： Digital adjustment of an oscillator is provided to adjust the oscillation frequency of the oscillator to perform the selective change of an oscillation frequency efficiently without the damping of the oscillator. Digital adjustment of an oscillator includes at least one pair of capacitors(C,C'), first field effect transistors(T1,T1'), a second field effect transistor(T2), and third field effect transistors(T3,T3'). The pair of capacitors have first terminals connected to the oscillator, and second terminals selectively connected to a first reference potential(vss) by the switching arrangement to integrate the capacitors with an oscillation circuit of the oscillator. The first field effect transistors individually connect the second terminals and the first reference potential. The second field effect transistor connects the second terminals to each other. The third field effect transistors individually connect the second terminals and a second reference potential(vdd) which is different from the first reference potential.
