Television tuner which operates at low voltage

A television tuner comprising:

• a tuning circuit which tunes with a television signal within a prescribed receiving frequency band;
• a high frequency amplifier which amplifies the television signal;
• a mixer which converts the television signal into an intermediate frequency signal;
• and
• an oscillating section which supplies a local oscillation signal to the mixer, wherein
• the tuning circuit is made up of an inductor and plural capacitors;
• wherein at least one of the capacitors is selected and connected in parallel with the inductor;
• wherein the oscillating section is made up of at least plural oscillators which are included in an integrated circuit;
• wherein in the integrated circuit, each of the oscillators has a variable capacitor to vary a frequency of the local oscillation signal;
• wherein groups into which the receiving frequency band is divided correspond to the oscillators on the basis of one oscillator per group;
• and
• wherein each of the oscillators generates local oscillation frequencies depending on television signals in the corresponding group.
