CERDEIRA-ESTRADA, A.; DE LUCA, A.; CUTTIN, A.  e  MUTIHAC, R.. Low noise low power readout circuit for soft X ray detection. J. appl. res. technol [online]. 2003, vol.1, n.3, pp.187-193. ISSN 2448-6736.

A new low power CMOS ASIC for the detection of X-rays was optimized for low power and low noise. Theoretical calculations and optimizations are presented and compared with experimental results. Noise as low as 120+25-C_in [pF] ENC rms was obtained including a silicon detector of 1.3 pF and 0.3nA of leakage. The power consumption is less than 100 W. Other circuit parameters are also shown.
