Low voltage temperature-independent and temperature-dependent voltage generator

An apparatus for generating a temperature-dependent voltage and a temperature-independent voltage, comprising:

• means for generating a feedback signal;
• means for generating a startup signal in relation to the feedback signal;
• means for removing power supply noise from the feedback signal and the startup signal;
• means for generating the temperature-independent voltage in relation to the feedback signal and the startup signal;
• and
• means for generating the temperature-dependent voltage in relation to the temperature-independent voltage.

A method for generating a temperature-dependent voltage and a temperature-independent voltage using a voltage generator having a power supply, comprising:

• generating a feedback signal;
• generating a startup signal, wherein the startup signal connects to the feedback signal;
• generating the temperature-independent voltage in relation to the feedback signal and the startup signal using a first temperature-sensitive element;
• and
• generating the temperature-dependent voltage in relation to the temperature-independent voltage, wherein the temperature-dependent voltage is generated using a second temperature-sensitive element.

A method for forcing a temperature-dependent and temperature-independent voltage generator out of a no-current state, comprising:

• generating a first temperature-sensitive voltage;
• generating a second temperature-sensitive voltage;
• generating a feedback signal by comparing the first temperature-sensitive voltage to the second temperature-sensitive voltage;
• generating a startup signal using the feedback signal;
• and
• inputting the startup signal to the feedback signal.
