The invention discloses a linear programmable switched capacitor gain amplifier. With the piecewise-linear concept, firstly, the whole gain curve is cut into a plurality of sections linearly; and then the linear gain adjustment of MSB and LSB is realized in the same gain stage. The linear programmable switched capacitor gain amplifier realizes the linearization by setting the sampling capacitor array, keeping each capacitor value in the capacitor array, matching the switch of the capacitor switch, sampling the capacitor array, and keeping the arrangement of the capacitor array; moreover, the function of the whole programmable gain amplification can be realized in the same stage, thereby not only simplifying the design, saving the cost, reducing the consumption of current, and being suitable for the expendability and carrying device.
