Transitioning from Normal Mode to Low-Power Retention Mode |
| 摘要 |
A retention mode manager circuit, including: a resistor and a capacitor configured as an RC filter, and the RC filter is configured to receive a retention voltage and output a filtered retention voltage; a retention amplifier configured to receive the filtered retention voltage at a first input terminal and to provide current to a load corresponding to the filtered retention voltage; and a transition amplifier configured to receive the filtered retention voltage and an offset voltage, and to guide the filtered retention voltage to make a transition to the offset voltage while minimizing undershoot or overshoot to prevent a loss of data in the load. |
