Asynchronous circuits implemented using threshold gate(s) and/or majority gate(s) (or minority gate(s)) are described. The new class of asynchronous circuits can operate at lower power supply levels (e.g., less than 1V on advanced technology nodes) because stack of devices between a supply node and ground are significantly reduced compared to traditional asynchronous circuits. The asynchronous circuits here result in area reduction (e.g., 3× reduction compared to traditional asynchronous circuits) and provide higher throughput/mm2 (e.g., 2× higher throughput compared to traditional asynchronous circuits). The threshold gate(s), majority/minority gate(s) can be implemented using capacitive input circuits. The capacitors can have linear dielectric or non-linear polar material as dielectric.
