Abstract: Provided is a switch having a structure having an excellent isolation characteristic even without a limiter in an ultrahigh frequency hand used for a military component. A switch according to an embodiment of the present invention comprises: multiple transistors which are connected in parallel to a path from an input terminal toward an output terminal and perform switching; and a first transmission line provided between the input terminal and a node on a path to which a first transistor is connected. By the present invention, switching can be performed in an ultrahigh frequency such as W-band while a GaN transistor is used, an insertion loss is low, an isolation characteristic is excellent, and eventually efficiency of an ultrahigh frequency circuit can be further enhanced.

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.
