Low power serial-parallel dynamic shift register

Serial-to-parallel shift registers have a wide range of applications. These registers are commonly found in communication systems and interfaces between electronic peripherals. Presented is a unique low power area efficient 128-bit serial-to-parallel shift register design that contains only four transistors per stage. The new register uses the capacitive bootstrapping technique to overcome the threshold voltage drop of MOSFETs. This logic family is named non-ratioed bootstrap logic (NRBL). Target applications are dense smart sensor arrays and image sensors.
