Bipolar junction transistor buffer

A buffer circuit, comprising:

• a PNP bipolar junction transistor (BJT) configured to receive a buffer input signal;
• an NPN BJT also configured to receive the buffer input signal;
• a first diode having a first cathode and a first anode, the first cathode coupled to the PNP BJT;
• a second diode having a second cathode and a second anode, the second anode coupled to the NPN BJT;
• a first voltage level shifter circuit coupled to the first anode, the first voltage level shifter having a first voltage level shifter output;
• a second voltage level shifter circuit coupled to the second cathode, the second voltage level shifter having a second voltage level shifter output;
• a first pre-driver circuit coupled to the first voltage level shifter;
• a second pre-driver circuit coupled to the second voltage level shifter output;
• a first transistor coupled to the first pre-driver circuit and an output of the buffer circuit;
• and
• a second transistor coupled to the second pre-driver circuit and the output of the buffer circuit.
