چکیده
This brief presents a survey of analog high frequency design challenges for continuous time integrator to be used in low pass ∑Δ Modulator. Such oversampling modulators are fast replacing old Nyquist based modulators in analog to digital converters used in RF front end of transceivers. Possible solutions to some of the most common but stringent analog issues are also presented. This communication is a unique literature survey and can guide through the design of challenging analog modules. Keywords-Gm-integrator, CMOS, non-idealities, continuous
