摘要
论证了输入电路中有稳压二极管的运放组成的方波发生电路产生的方波周期将明显小于理论估算值。由此要求设计者在使用运放设计电路时,必须注意电路所需的参数指标及芯片内部结构,选用合适的运算放大器。
Square-wave circuit composed of operational amplifiers that have diodes for protection in input circuit,generated square-wave cycle that was smaller than theoretical estimates.Using operational amplifier to design circuit,designer must pay attention to parameter indicators for circuit and the internal structure of chips,and select appropriate operational amplifiers.
