Abstract: A low noise comparator for a high resolution ADC is provided. The comparator includes: an inputter configured to receive a signal and amplify the signal; and an outputter configured to output a result of comparing the signal output from the inputter, wherein an inductor is connected to an input terminal of an input element of at least one of the inputter and the outputter. Accordingly, the comparator can satisfy the gain value and the noise performance at the same time by using the inductor which has no voltage headroom problem.

Abstract: A radio frequency (RF) switch with a transformer and a switching method thereof are provided. The RF switch includes a transmitting end transformer having a primary side connected to a transmitting end and a secondary side connected to an antenna; and a receiving end transformer having a primary side connected to the antenna and a secondary side connected to a receiving end. In a transmission mode, the transmitting end transformer is tuned on, and, in a reception mode, the receiving end transformer is turned on. Accordingly, since switching is performed based on transformers rather than transistors connected in series, the RS switch, which can achieve high linearity and low insertion loss as well as high isolation, can be implemented.
