Abstract

An oscillator for high-frequency signal generation is disclosed. Provided according to the present invention is an oscillator for high-frequency signal generation comprising: a first transistor comprising a first collector for receiving a power supply voltage from a load, a first base connected to a ground, and a first emitter connected to the first base; and a second transistor comprising a second collector for receiving a power supply voltage from the load, a second base connected to a ground, and a second emitter connected to the second base, the oscillator having a common-base cross-coupled structure in which the first collector and the second emitter are cross-coupled and the second collector and the first emitter are cross-coupled.

First claim

The invention claimed is:

1. A common-base cross-coupled oscillator for high-frequency signal generation, the oscillator comprising:
a first transistor including a first collector receiving a power supply voltage from a load, a first base connected to a ground, and a first emitter connected with the first base;
a second transistor including a second collector receiving the power supply voltage from the load, a second base connected to the ground, and a second emitter connected with the second base;
a first capacitor connected between the first collector and the first base;
a second capacitor connected between the second collector and the second base; and
the oscillator having a common-base cross-coupled structure in which the first collector and the second emitter are cross-coupled and the second collector and the first emitter are cross-coupled.

2. The common-base cross-coupled oscillator of claim 1 , further comprising:
a feedback impedance element connected each between the first collector and the second emitter and between the second collector and the first emitter.

3. The common-base cross-coupled oscillator of claim 1 , further comprising:
a base-emitter impedance element connected between the first base and the first emitter and between the second base and the second emitter.
