IEEE JSSC固态电路模拟设计DC-DC转换器扬声器保护
▸创新点1:类D智能扬声器驱动器 - 该系统创新结合了DC-DC升压转换器,确保在低电池电压下仍能维持最大输出功率,显著提升了音频放大器的效率和稳定性。
▸创新点2:DC-DC升压转换器 - 该电路创新通过高效能转换技术,使得类D放大器和DC-DC升压转换器的组合效率在全功率输出时超过80%,大幅提升了能源利用率。
▸创新点3:扬声器保护算法 - 该方法创新利用嵌入式DSP运行保护算法,通过精确测量扬声器电流(相对误差小于2%),实时估计膜片位移和音圈温度,有效防止扬声器损坏。
▸创新点4:采样保持技术 - 该电路创新采用采样保持技术,在瞬时负载电流等于平均电流时进行采样,有效抑制负载电流纹波,进一步提升了系统的稳定性和精度。
Abstract
al Issue of the IEEE J OURNAL OF SOLID-STATE
CIRCUITS is dedicated to the best papers taken from the
Analog, Data Converter, RF, Wireless, and Wireline Communi-
cations sessions at the IEEE International Solid-State Circuits
Conference (ISSCC) in San Francisco, CA, USA, held in Feb-
ruary 2013. As always, selecting a subset of papers from these
high quality sessions proved to be a dif ficult task. However, we
hope that the papers included in this issue are representative of
the key innovations se
