Analog break before make system, method and apparatus |
摘要 |
A system and method of providing an analog make before break circuit includes a first transistor coupled in series with a second transistor, the first transistor being configured for conducting a high portion of an input signal, the second transistor being configured for conducting a low portion of the input signal. A third transistor is configured to interrupt a connection between the input signal and a first transistor input node, the third transistor having a third transistor threshold voltage between of about 90 and about 110 percent of a second transistor threshold voltage. A fourth transistor is configured to interrupt a connection between the input signal and a second transistor input node, the fourth transistor having a fourth transistor threshold voltage of between about 90 and about 110 percent of a first transistor threshold voltage. |

1. An analog make before break circuit comprising:
a first transistor coupled in series with a second transistor, the first transistor being configured for conducting a high portion of an input signal, the second transistor being configured for conducting a low portion of the input signal; and a first interrupt device coupled between the input signal and a first transistor input node, the first interrupt device configured to interrupt coupling the input signal to the first transistor input node when the second transistor is in a conducting state, the first interrupt device including a first logic gate, the first logic gate being disabled until the second transistor is in a non-conducting state. |
