Abstract
En 中文
Microdisplays are a key component in many contemporary portable electronic systems. Microdisplays consume a large fraction of the overall energy of the system, and therefore, there is a desire to reduce its energy and extend the battery life. This paper proposes circuit techniques to recycle energy in the row driver and reduce its dynamic power consumption. The measurement results on proof-of-concept arrays implemented in TSMC 65 nm technology show a 24%, 29%, and 30% reduction in the power consumption of the row driver using the one-capacitor, two-capacitor, and direct energy recycling techniques, respectively. Applying these techniques reduces up to more than 45% of the dynamic power consumption of the row driver.
