Ultra-low power CMOS cells for temperature sensors
Temperature sensors and voltage references require cells that generate both PTAT (Proportional To Absolute Temperature) and NTC (Negative Temperature Coefficient) voltages. We pre...

Design and power optimization of CMOS RF blocks operating in the moderate inversion region
In this work the design of radiofrequency CMOS circuit blocks in the 910MHz ISM band, while biasing the MOS transistor in the moderate inversion region, is analyzed. An amplifier ...

New low-voltage electrically tunable triode-MOSFET transconductor and its application to low-frequency Gm-C filtering
A new low-voltage electrically tunable transconductor is presented. Its transconductance can be settled by means of a ratio between a reference current and a reference voltage ren...

Current mask generation: a transistor level security against DPA attacks
The physical implementation of cryptographic algorithms may leak to some attacker security information by the side channel data, as power consumption, timing, temperature or elect...
