I need a active safety circuit to clamp voltages to the range of 0-0.2mV, independent of temperature and very precisely. I have simulated, using TINA-TI, 4 precision clamps in series to do this, see design below: the first two precision clamps ensures the lower clamp voltage and the last two ensures the top clamp voltage. There is an offset for some reason if the buffer is not included.

However, this is a very component heavy design, and I'm wondering if there is a simpler method? Thanks for reading.
