摘要： A switching circuit that transitions using a switch transistor. During the initial stages of a high-low transition, a control loop provides supplemental pre-charge to the gate of the switch transistor to reduce high-low switching delays. Once the current flowing through the switch transistor rises to a level causing the output voltage to change at specified speed threshold, a loop opening mechanism opens the loop. Further opening of the switch transistor in the high-low transition is taken care of by a relatively constant current source. At that point, no or negligible feedback current is used to charge the gate of the switch transistor. Low-high transitions may be performed in a similar complementary manner.

摘要： A signal generation circuit that uses a waveform generation mechanism to generate predetermined waveform(s) when triggered. A triggering mechanism is configured to repeatedly trigger the waveform generation mechanism at times that are dependent on data provided by a data source. The predetermined waveform may be a bandwidth-limited pulse, but might also be a rising edge or a falling edge of a pulse. Various consecutive waveforms may be summed together to thereby formulate a continuous signal. The waveform may have particular characteristics by design.

摘要： A track and hold (or sample and hold) offset compensated amplifier circuit that performs offset compensation in response to a comparison of sign (or sign and value) of the current forced to the output terminal of operational amplifier in order to keep it at the potential of holding capacitor during the holding phase. Based on this comparison, the comparison circuit increases or decreases the voltage differential applied between the positive and negative input terminals of the operational amplifier depending on whether the comparison circuit detects that the current forced to the output terminal of the operational amplifier is positive or negative. During the holding phase, negative feedback is disconnected, and the positive and negative input terminals of the operational amplifier are connected.
