nmos晶体管 meaning in Chinese
nmos transistor
Examples
- This is due to the fact that each transistor in a cmos circuit is actually made from a pmos transistor and an nmos transistor
这是由于cmos里的每一个晶体管都是由一个pmos和一个nmos晶体管组成的。 - Compared with the similar research results , the weighted control ic here has the following characteristics : ( 1 ) the circuit structure is simpler ; ( 2 ) the chip ' s fabrication is compatible with standard cmos process ; ( 3 ) n - mosfets with high w / l ratio and short channels are used for weighting and output to reduce the insertion loss ; ( 4 ) the weighting factor varies in a relatively wide range with the controlling signals ; ( 5 ) input and output impedance approach 50 in low frequency ( e . g . 50mhz ) , while in higher frequency they slightly deviate from 50 , hence the energy reflection lower than 0 . 1 ; ( 6 ) it completes the functions of sampling , weighting , controlling and summing of high frequency analog signals
它的加权控制电路与已报道的相关电路相比具有如下特点：电路结构简单；制造工艺与普通cmos工艺兼容：短沟道，高宽长比的nmos晶体管具有低的通导电阻，将其作为加权、输出器件可降低由电路引起的插入损耗；改变加权信号，可实现权值在较大范围内的连续变化；输入、输出阻抗在低频(如50mhz )下接近50 ，而在高频下略有偏离50 ，但反射系数均低于0 . 1 ；实现了对高频信号的取样、加权、控制、叠加功能的迭加。 - A switch ic for analog signal processing is designed and implemented , which can fulfill the functions of sampling , weighting , controlling and summing of high frequency analog signals . the circuit consists of three parts : four channel analog switches , a voltage reference and the control circuitry . each analog switch is comprised of two high - transconductance n - mosfets with high w / l ratio , which realize the fine tuning and coarse tuning of the input signal respectively
本文研究并设计了一种可对高频信号进行取样、加权、控制、叠加的模拟信号处理丌关集成电路，它包括模拟开关、电压基准源和移位寄存器三个功能模块，通过两个高宽长比的高跨导nmos晶体管实现权值的粗调和微调。
