一种用于收集卫星信号的接收器的集成电路芯片
摘要：
一种集成电路芯片，包括一第一单端至差动放大器用以产生与该第一单端至差动放大器的一输入有关的一差动输出；一第二单端至差动放大器用以产生与该第二单端至差动放大器的一输入有关的一差动输出；一第一组开关电路位于该第一单端至差动放大器的信号下游端；一第二组开关电路位于该第二单端至差动放大器的信号下游端；以及一第一差动至单端放大器位于该第一组开关电路的一第一开关电路的信号下游端及位于该第二组开关电路的一第二开关电路的信号下游端。
摘要（英）：

An integrated circuit chip includes a first single-ended-to-differential amplifier configured to generate a differential output associated with an input of said first single-ended-to-differential amplifier; a second single-ended-to-differential amplifier arranged in parallel with said first single-ended-to-differential amplifier; a first set of switch circuits arranged downstream of said first single-ended-to-differential amplifier; a second set of switch circuits arranged downstream of said second single-ended-to-differential amplifier; and a first differential-to-single-ended amplifier arranged downstream of a first one of said switch circuits in said first set and downstream of a first one of said switch circuits in said second set.
