A fully-integrated series resonant class DE inverter is realized in a 130 nm 1.2 V CMOS technology with an on-chip spiral inductor and an integrated MIMcap. It is used as the first stage in fully-integrated class DE DC-DC resonant converters. The inherent soft switching yields high conversion efficiency at high switching frequencies. Low switching peak-voltages are present in the circuit, alleviating the need for on-chip high-voltage techniques. The use of on-chip passives reduces the bill of materials (BOM) considerably. The maximum output power of the series resonant class DE inverter is 11.6 mW. The maximum power efficiency is 65.2 %. The measurement results confirm and improve previous simulations.
