Abstract: Provided are a microfluidic control scheduler circuit and a the lab-on-a-chip. The microfluidic control scheduler circuit includes an input channel serving as a flow path between an input port and a membrane capacitor, a gate supply channel serving as a flow path between the membrane capacitor and a main valve, a gate supply port connected to the gate supply channel via a fluid resistance channel and a relief valve, and a scheduler module including an output channel serving as a flow path between a source supply port and an output port via the main valve, wherein the scheduler module is provided in plurality. The microfluidic control scheduler circuit and the lab-on-a-chip according to the present disclosure may sequentially and independently control a certain process without external control, thereby automating the lab-on-a-chip for processing a microfluid.
