    High performance and energy efficiency are very crucial aspects in e.g. the field of edge computing where a tight power budget constrains the device operation. Different logic families were explored over the years to design standard cells with higher performance and/or lower power while keeping the noise immunity and the compatibility with design automation tools intact. Hybrid pass transistor logic with static CMOS output (HPSC) seems to be promising and is exploited in this paper to design low energy, high performance and toolchain-compatible standard cells without compromising on noise immunity and chip area. This paper presents a 2/3-input XOR cell, a 2/3-input XNOR cell, two variants of a half adder cell, a full adder cell and two variants of a 1-bit multiply-accumulate combinational cell based on a combination of HPSC and static CMOS logic in a commercial 65nm Low-Power CMOS technology. Post-layout simulations over all the process-voltage-temperature corners show a 4.7% - 35.7% lower energy-delay product with significant improvement in the propagation delay of the proposed cells.
