Analog building blocks for a sampled data fast wavelet transform CMOS VLSI implementation

A set of high performance analog blocks, used for a sampled data fast wavelet transform chip, is presented. Use of novel techniques based on multiple-input floating-gate MOS transistors enhances the circuit characteristics. Control circuits using these devices allow one to improve behavior parameters such as bandwidth, distortion, common-mode, and unity-gain compensation. An improved voltage follower circuit using these blocks is discussed. Simulation results are presented.
