Abstract
A signal amplifying system having an oscillator and an amplifying circuit. The oscillator has a first resistor with a first resistance Rand a first capacitor with a first capacitance C, and generates an oscillating signal having a frequency f which equals to k1/(R*C), k1 is a first proportional parameter. The amplifying circuit has an input terminal to receive an input signal and amplifies the input signal under the control of the oscillating signal. The amplifying circuit has a second resistor with a second resistance Rand a second capacitor with a second capacitance C. The amplifying circuit has a −3 dB bandwidth Wwhich equals to k2/(R*C), k2 is a second proportional parameter. In this signal amplifying system, the product of the first resistance Rand the first capacitance Cis proportional to the product of the second resistance Rand the second capacitance C
