Abstract

Several latch circuits including a NAND gate stage and combinations of clocked inverter stages and inverter stages are described. A programmable frequency divider including homologue frequency divider circuits using the latch circuits is also described. Also described is a circuit included in the homologue frequency divides and a method for correcting the duty cycle of clock signals generated by the homologue frequency dividers to 50%.
