Abstract: A circuit including a digital-to-analog converter (DAC) having a first terminal and a second terminal. The circuit also includes a first diode having a first terminal coupled to the second terminal of the DAC and having a second terminal coupled to the first terminal of the DAC. A comparator has a first terminal and a second terminal. A second diode has a first terminal coupled to the second terminal of the DAC and has a second terminal coupled to the second terminal of the comparator. A voltage-to-current converter (V2I) has a terminal. A resistor has a first terminal coupled to the second terminal of the second diode and has a second terminal coupled to the terminal of the V2I converter.

Abstract: A circuit includes a first transistor, a second transistor, a third transistor, a fourth transistor, and a fifth transistor. A first terminal of the second transistor is coupled to a control terminal of the first transistor. A second terminal of the second transistor is coupled to a second terminal of the first transistor. A first terminal of the third transistor is coupled to a voltage supply terminal. A second terminal of the third transistor and a first terminal of the fourth transistor are coupled to a control terminal of the second transistor. A second terminal of the fourth transistor is coupled to the second terminal of the second transistor. A first terminal of the fifth transistor is coupled to a first terminal of the first transistor. A second terminal of the fifth transistor is coupled to a control terminal of the fourth transistor.
