摘要: A transconductance control circuit of a rail-to-rail differential input stage is described. The transconductance control circuit senses the gate-source voltages of PMOS and NMOS differential pairs, converts the sensed voltage to a current, compares the current with a reference current, and controls the currents of the PMOS and NMOS differential pairs to control the transconductance of the RTR differential input stage. Also, various types of biasing techniques and matching techniques are used to reduce the variations of the transconductance.

摘要: A high voltage gate driver circuit according to an embodiment of the present invention controls an operational range of an output signal of a level shifter to be appropriate for an operational range of a reshaper through a VIV converter. Even though the voltage range of the signal which is input from the high voltage gate driver circuit to the level shifter is different from the operational range of the reshaper, the input signal can always be recognized exactly regardless of the VTH voltage of the reshaper by controlling the operational range of the signal through the VIV converter. In addition, incorrect operation of the circuit can be prevented by erasing a common mode noise which is input with the input signal.
