Abstract
A system includes: 1) a buffer circuit; 2) circuitry coupled to an input of the buffer circuit; 3) a load coupled to an output of the buffer circuit; and 4) a clamp circuit coupled between an input of the buffer circuit and the output of the buffer circuit. The clamp circuit includes: 1) a bipolar junction transistor (BJT); 2) a first resistor with a first end coupled to a base terminal of the BJT and with a second end coupled to a collector terminal of the BJT; and 3) a second resistor with a first end coupled to the collector terminal of the BJT and with a second end coupled to the input of the buffer circuit. The second resistor is between an output of the circuitry and the input of the buffer circuit.
