| Abstract(in English) | In this report, additive noise from Switched Capacitor Filter (SCF) section in Direct Sampling Mixer (DSM) was analyzed. The influence of on-resistances of MOS switches does not depend on the on-resistance value, but on the value of capacitance which constitutes SCF section. And, it was confirmed by the transient simulation that this result of the analysis is appropriate. Moreover, the design method of low noise DSM was examined by comparing the noise output from SCF section with the gain of desired signal and thermal noise from Transconductance Amplifier (TA) in consideration of its parasitic impedance. |
