About Attohenries
The attohenry (aH) equals 10⁻¹⁸ H, the scale for parasitic inductances in on-chip metal interconnects and quantum-device bondwires. Metal traces in sub-10 nm CMOS processes have via-to-via inductances in the attohenry range; superconducting qubit junctions are modelled with loop inductances of tens to hundreds of attohenries; microwave integrated circuit (MMIC) vias at 100 GHz are characterised in aH. 1 aH = 10⁻³ fH = 10⁻¹⁸ H.
About Picohenries
The picohenry (pH) equals 10⁻¹² H, the practical unit for short PCB traces, decoupling capacitor equivalent series inductance (ESL), and bond-wire inductance in RF packages. A 1 mm PCB trace (50 Ω microstrip) has about 1 nH/mm; SMD bypass capacitors have ESL of 0.1-2 nH; gold bondwires are 1-5 pH/mm. IC package lead inductances are typically 1-10 nH = 1 000-10 000 pH. 1 pH = 10⁻³ nH = 10⁻¹² H.
