However, FETs with low threshold voltage (say 0.4 V or lower) will turn on at a lower voltage than a diode will, and this can be useful in low voltage circuits.
WebWhen a diode-connected MOS transistor is biased with a PTAT current source, the gate-source voltage of such tran-sistor can be temperature independent. Based on this idea a circuit is designed and implemented in a standard 0.18-µm CMOS technology. The simulations show that the output voltage of this reference has the temperature …
