【摘要】：当前电子传感接收电路具有能耗高、性能参数不符合要求的弊端。为此,设计一种新的基于CMOS的电子传感接收电路,并介绍了电子传感接收电路设计方案。依据设计方案,选用源级负反馈电感匹配结构对低噪声放大器的基本电路结构进行设计;为达到性能指标和降低功耗,混频器电路结构选用无源双平衡混频器结构;为了降低整个电子传感接收电路的能耗,令无源双平衡混频器的开关MOS管在无电流偏置的情况下运行。给出了复数滤波器设计的基本思想,通过反馈系统对编程增益放大器的增益进行管理,实现可编程放大器的设计。实验结果表明,所设计电路性能符合设计要求。
[Abstract]:The current electronic sensor receiving circuit has the disadvantages of high energy consumption and nonconforming performance parameters. In this paper, a new CMOS based electronic sensor receiving circuit is designed, and the design scheme of the electronic sensor receiving circuit is introduced. According to the design scheme, the basic circuit structure of the low noise amplifier is designed with the source level negative feedback inductor matching structure, and in order to achieve the performance index and reduce the power consumption, the circuit structure of the mixer adopts the passive dual balanced mixer structure. In order to reduce the energy consumption of the whole electronic sensing receiving circuit, the switching MOS transistor of the passive dual-balanced mixer is operated without current bias. The basic idea of the complex number filter design is given. The gain of the programmable gain amplifier is managed by the feedback system to realize the design of the programmable amplifier. The experimental results show that the designed circuit meets the design requirements.
