| titleOfInvention | Pipeline analog-to-digital converter and operational amplifier self-adaptive configuration circuit and method thereof |
| abstract | The invention provides a pipeline analog-to-digital converter and an operational amplifier adaptive configuration circuit and method thereof. The operational amplifier self-adaptive configuration circuit comprises a residual error step detection module, a configurable negative resistance unit array and a self-adaptive configuration control module. After the operational amplifier self-adaptive configuration circuit is powered on, under the control of the self-adaptive configuration control module, the residual error step detection module automatically adjusts and configures the negative resistance unit array by detecting the residual error step of the circuit to be calibrated when zero input occurs, so as to maximize the open loop gain of the operational amplifier. The operational amplifier self-adaptive configuration circuit can be compatible with a foreground calibration circuit of a stage circuit capacitor mismatch error, and has the advantages of simplicity, high efficiency and small area overhead compared with a traditional operational amplifier limited gain error calibration circuit. |
