This paper presents a compact digitally controlled variable gain amplifier (DVGA) with capabilities of both temperature compensated linear-in-decibel (dB-linear) gain control and DC offset cancellation (DCOC) without making use of either the feedback or the feed-forward loop. The proposed DVGA desig...
