LOW POWER VTT GENERATION MECHANISM FOR RECEIVER TERMINATION

Systems, apparatuses, and methods for performing efficient data transfer in a computing system are disclosed. A termination voltage generator includes an inverter-based chopper circuit, which uses a first group of an even number of serially connected inverters coupled between the output node of the chopper circuit and the gate terminal of an output pmos transistor. Additionally, a second group of an even number of serially connected inverters is coupled between the output node and the gate terminal of an output nmos transistor. A replica inverter includes two serially connected pmos transistors and two serially connected nmos transistors. Each of one pmos transistor and one nmos transistor receives a generated voltage set as the expected value of the termination voltage. Each of the other pmos transistor and nmos transistor receives an output based on a comparison between the expected value to the output of the replica inverter.
