摘要： A digital phase detector includes a quantization unit that quantizes a frequency of a reference signal to generate reference delay information and reference integer phase information, and quantizes a frequency of an oscillation signal to generate oscillation delay information and oscillation integer phase information. A first conversion unit converts the frequency of the reference signal into reference frequency information based upon the reference delay information and the reference integer phase information. A second conversion unit converts the frequency of the oscillation signal into oscillation frequency information based upon the oscillation delay information and the oscillation integer phase information. A calculation unit converts the reference frequency information and the oscillation frequency information into first and second phase information, respectively, and outputs a digital phase difference between the first phase information and the second phase information.

摘要： A linear mixer circuit with a current amplifier has an excellent linearity by using RF open-load and an improved current amplifier. Therefore, a voltage-current converting stage and a current-voltage converting stage in a conventional mixer circuit can be omitted. Further, by using the RF open-load and the current amplifier together, a current type input signal can be transmitted as it is, and non-linearity due to the voltage-current converting stage and the current-voltage converting stage can be prevented. Furthermore, bias current of the amplifying stage and the switching stage can be separated by using the RF open-load, so that an image frequency can be filtered by the RF open-load.
