A level-shifting inverting circuit provides a blanking signal to Grid 1 of
a CRT. The circuit provides the blanking signal from a blanking logic
signal according to a voltage transfer characteristic that is
substantially similar to the voltage transfer characteristic of a
standard CMOS inverter. Also, the level-shifting inverting circuit
includes a switch circuit that includes a differential pair. The
differential pair has the blanking logic signal at one input, and a bias
signal at the other input. The switch circuit is coupled to a voltage
divider that provides an output voltage that is pre-determined by a
resistor ratio when the switch circuit is open. If the blanking logic
signal is low, the switch circuit is open. Conversely, if the blanking
logic signal is high, the switch circuit is closed, and sinks current
from the voltage divider, causing the output voltage to correspond to a
second pre-determined voltage level.
