Circuit and method of previewing analog trimming |
摘要 |
An analog trim circuit enables and disables one or more serially connected passive elements for setting characteristics of the circuit. Each passive element has a transistor across its first and second conduction terminals operating in response to a control signal from a control circuit for enabling and disabling conduction through the associated passive element. The control circuits are responsive to a data signal for providing the control signals that enable and disable the conduction through the passive elements. The data signal allows a preview of the trimming results. The fuse in certain ones of the control circuits are blown to set the control signals to fixed values after removal of the data signal.
