Abstract:
A signal amplifying system having an oscillator and an amplifying circuit. The oscillator has a first resistor with a first resistance R 1  and a first capacitor with a first capacitance C 1 , and generates an oscillating signal having a frequency f which equals to k1/(R 1 *C 1 ), 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 R 2  and a second capacitor with a second capacitance C 2 . The amplifying circuit has a −3 dB bandwidth W −3 dB  which equals to k2/(R 2 *C 2 ), k2 is a second proportional parameter. In this signal amplifying system, the product of the first resistance R 1  and the first capacitance C 1  is proportional to the product of the second resistance R 2  and the second capacitance C 2.
