About Attofarads
The attofarad (aF) equals 10⁻¹⁸ F, the scale for quantum-mechanical and nanoscale capacitances. Carbon-nanotube transistor gate capacitances are 1-100 aF; single-electron tunnel junctions in Coulomb-blockade devices operate in the attofarad range; scanning-probe microscopy tip-sample junctions at sub-nanometre separation approach 1 aF. 1 aF = 10⁻³ fF = 10⁻¹⁸ F.
About Picofarads
The picofarad (pF) equals 10⁻¹² F, the everyday unit for small-signal capacitors in RF and high-frequency circuits. Ceramic chip capacitors range from 0.5 to 100 pF; crystal oscillator load capacitance is typically 12-22 pF; PCB trace-to-trace coupling is 0.1-10 pF/cm; the human body presents roughly 100 pF at radio frequencies. 1 pF = 10⁻³ nF = 10⁻¹² F.
