Abstract (en)
[origin: WO2011063101A1] The disclosed invention provides chopper stabilized amplifier circuitry (100) having a gain stage (107). The input (110) and output (112) of the gain stage (107) are each chopped. Integrator circuitry (113) is provided the chopped gain stage output signal may be integrated, and low pass filter circuitry (120) is operably coupled between the integrator (113) and the chopper stabilized amplifier circuit output (104), whereby the signal may be sampled, filtered, and conducted to the output (104).
