The chip has been realized in 0.35μm 2P4M CMOS technology. The amplifier features an open-loop gain of 83.9dB and a GBW of 10MHz. The measured typical residual input offset is less than 93.7μV,and the equivalent input low frequency noise is 19.6nV/Hz at a chopping frequency of 100kHz and supply voltage of 3.3V.
The results of the stimulation, based on the Spectre software with 0.35μm Bi CMOS technology module, showed that the amplifier had a open loop plus of more than 60dB, a unit plus bandwidth of more than 2.1 GHz and an output amplitude of 1.5V.
