Low dissipation current GaAs prescaler IC

A 1 GHz variable modulus freqency divider with very low dissipation current has been developed. Using a high-transconductance (200?250 mS/mm) FET by Pt burying technology and series gating source-coupled FET logic, the dissipation current of the fabricated IC was reduced to 3.2 mA at 1 GHz operation.
