An RF front-end circuit for a fully integrated CMOS DTV tuner is presented in this paper, where double-conversion low IF architecture is employed.
该电路采用二次变频低中频结构，集成了低噪声放大器、上变频混频器、下变频混频器等模块。
In Table 1, if all related architecture counters are low, this suggests that the system does not suffer from any system bound actions.
在表1中，如果所有相关的架构计数器为低，这暗示系统没有遭受任何系统限制动作。
If low level of parallelism is considered, multicomputer architecture is better than multiprocessor architecture.
若考虑较低的层次，多重电脑架构实为较理想的平行控制架构。
The architecture of zero IF receivers that has the advantage of low-cost, low power dissipation and small from factor is gaining interest while developing OFDM terminal.
为了研制低价格、低功耗、小尺寸的OFDM终端，零中频的接收机结构越来越倍受关注。
