摘要
En 中文
This paper describes a technique for exploiting circuit instability to achieve baseband linear amplification. The input signal is periodically sampled by a first-order unstable circuit, and amplification is achieved by the exponentially growing natural response. A low-pass sampled amplifier response is achieved. An operational amplifier implementation of the circuit is described, and the main practical limiting factors are presented. Several applications and experimental results are provided.
