Comparator-based drivers for LCD displays and the like
A comparator-based driver has a configurable inverter that inverts one of the comparator output signals for application to the gate of a driver transistor used to generate the driver output signal. The configurable inverter can be selectively configured to provide any one of at least two different i...

| description | A comparator-based driver has a configurable inverter that inverts one of the comparator output signals for application to the gate of a driver transistor used to generate the driver output signal. The configurable inverter can be selectively configured to provide any one of at least two different inverter logic threshold levels. In one possible operational scenario, the configurable inverter is configured such that the inverter logic threshold level is equivalent to the comparator's differential common-mode voltage to provide relatively high driver symmetry. The configurable inverter is then configured to provide a different inverter logic threshold level that is greater than the comparator's differential common-mode voltage to inhibit chattering in the driver output signal. |
