A Controllable Constant Power Generator in 0.35 μm CMOS Technology for Thermal-Based Sensor Applications

Figure 13

The generated power P_L = 5 mW of the proposed controllable constant power generator versus load resistance for temperatures T∈{−20°C, −10°C, 0°C, 10°C, 20°C, 30°C, 40°C, 50°C, 60°C, 70°C, 80°C}, with temperature-dependent resistors. The current −I(R_L) is, in fact, the current I_L. The voltage V₂(R_L) is the voltage V_L.
