| Abstract: | This paper presents the general formalizations of a Digital RF charging sampling mixer in theory,and a mixed-signal modeling method based on Verilog-AMS language and circuit-based macro models in SpectreRF.Using the method,a mixed-signal model of the multi-tap direct sampling mixer is constructed and simulated.In order to use RF-oriented algorithms in SpectreRF,the paper presents a new structure based on frequency dividers,decimators and phase adjustment units to solve the hidden-state problem when construc... |
