摘要
仅当输入变量较小时,运放的差动输入级可近似线性放大.本设计用反双曲正切变换电路,有效扩大了输入变量的变化范围,利用Pspice得到了预期的仿真结果.
Only as the input variables is smaller, differential input stage of operational amplifier can approximate linear magnifying. The design effectively enlarges the range of input variables using transform circuit of the inverse tanh, and obtains expected simulation results based on Pspice.
