Estimating the term…
A programmable gain amplifier includes a first-stage operational transconductance amplifier (OTA), a second-stage OTA, a capacitor module, a clock oscillation circuit, and a correction circuit. An input terminal of the second-stage OTA is connected to an output terminal of the first-stage OTA. The capacitor module is connected between the output terminal of the first-stage OTA and an output terminal of the second-stage OTA. The clock oscillation circuit is connected to the output terminal of the first-stage OTA and the capacitor module, and is configured to perform charging and discharging of the capacitor module by an output current from the first-stage OTA to output a clock signal. The correction circuit is connected to the clock oscillation circuit and the capacitor module to adjust a capacitance of the capacitor module so that a clock frequency of the clock signal is consistent with a preset clock frequency.
