20150084895 | LOAD DRIVING METHOD, LOAD DRIVING CIRCUIT, AND APPLICATION DEVICES THEREOF - The present invention discloses a load driving circuit, comprising a voltage differential generation circuit and a common mode voltage generation circuit; wherein the voltage differential generation circuit is configured to generate a driving voltage for driving a load; and the common mode voltage generation circuit is configured to: when the voltage differential generation circuit generates the driving voltage for driving the load, regulate the voltages output by a first output terminal and a second output terminal of the voltage differential generation circuit to the same voltage value. The present invention also provides a load driving method and application devices thereof. With the technical solutions according to the present invention, a central value of a voltage output by the first output terminal and a voltage output by the second output terminal of the voltage differential generation circuit is effectively regulated. In this way, when a duty cycle of an input signal is within a range of 0 to 100%, the driving voltage generated by the voltage differential generation circuit is in a linear relation with the duty cycle of the input signal, thereby ensuring fidelity of an output signal. | 03-26-2015 |
20150236699 | INPUT BUFFER CIRCUIT, METHOD, AND INTEGRATED CIRCUIT - This document discusses, among other things, an input buffer circuit, an input buffer method, and an integrated circuit, the input buffer circuit raising, using a potential raising device, a potential of a first reference ground to a potential of a second reference ground of an input stage, and improving a trigger voltage of the input stage.
