| 20100225395 | Input Buffer With Impedance Cancellation - An exemplary negative impedance converting circuit for functioning as a voltage buffer and/or negating the impedance of a connected load. The negative impedance converting circuit includes inputs, outputs, a first transconductance stage and a second transconductance stage. The transconductance gain value of the first transconductance stage is greater than a transconductance gain value of the second transconductance stage. Exemplary embodiments of a reference voltage buffer using the negative impedance converting circuit are also described. | 09-09-2010 |
| 20080197826 | SWITCHING POWER SUPPLY CONTROLLER WITH TRANSIENT GAIN CHANGE - A switching power supply controller has a nominal loop gain and transient loop gain that is only activated in response to an abrupt load change in one direction. The transient loop gain may be implemented with a series-connected diode and resistor combination arranged in a feedback configuration with an error amplifier. A large load change in one direction may swing the output of the error amplifier and forward bias the diode to create a non-linear gain change. | 08-21-2008 |
