摘要： In embodiments of the present invention, the problems of poor low-frequency response, slow speed, high cost and high power consumption in conventional voltage translators are addressed by processing high frequency and low frequency components of an input signal separately in two parallel stages (102,104) without the use of large passive components or slow devices. At the output, the processed high frequency and low frequency components are seamlessly merged at a combining stage (112) that maintains the integrity of the frequency response over the complete translator bandwidth.

摘要翻译： 在本发明的实施例中，常规电压转换器中的低频响应差，低速，高成本和高功耗的问题通过在两个并联级中分别处理输入信号的高频和低频分量来解决（102,104 ），而不使用大的无源组件或慢速设备。 在输出端，经处理的高频和低频分量在组合级（112）无缝地合并，该组合级保持了整个转换器带宽上的频率响应的完整性。
