The oscillator provides N oscillating signals with different phases. The assistant measuring circuit includes N buffers, N reflection-type modulators, and a controller. An ith buffer among the N buffers receives and further transmits an ith oscillating signal among the N oscillating signals. An ith modulator among the N modulators has an ith signal input end, an ith signal output end, and an ith signal control end. The ith oscillating signal is transmitted to the ith signal input end through the ith buffer. The signal output ends of the N modulators are all electrically connected to a measuring end. The controller is used for providing an ith control signal to the ith signal control end. | 12-10-2009 |
