Abstract :
A frequency divider is an essential circuit of a phase lockedfrequency stable oscillator. The operation of the regenerative Miller divider is described and three design methods for the regenerative dividers are presented. An MMIC Miller-type frequency divider byitwo for 40 GHz has been designed and realized The designed circuit was processed using 0 25 gm GaAs HEMT technology of THOMSON-CSF. The fractional bandwidth of 7 % was achieved with the input power of -3 dBm, when the conversion gain was about 8 dB.
