Abstract
An apparatus and method for manufacturing low-cost high-density compact active inductor module using existing DRAM, SRAM and logic process integration. The elements of the active inductor modules are formed by three semiconductor devices including nMOS devices, deep-trench capacitors and a polysilicon or TaN resistor. The active inductor modules can be connected in a parallel and/or serial configuration to obtain a wide range of inductance values. The modular active inductors can be advantageously stored in an ASIC library to facilitate a flexible and convenient circuit design.
