I use a piecewise linear approximation to achieve logarithmic function.
When I simulate the RSSI transfer curve, the dynamic range is very low.
I think it is due to the poor performance of Full wave rectifier.
How can I know that the full wave rectifier(FWR) is good enough?
according to the Katsuji Kimura paper, the input range of our FWR is from 0.1V to 0.4V. i think it is too low. usually what is the input range of the FWR I should achieve to have a good RSSI result?
NOTE : 1) FWR is moade up of an un-balanced source coupled pairs with cross-coupled outputs, whose inputs are connected in parallel.
2) our process is 0.18um SMIC
