Session: ANALOG & RF IC DESIGN Programmable CMOS APC/PAC circuit to control PAs and PA modules

چکیده
Today's market of Power Amplifiers (PAs) offers both PAs stand-alone and PA modules (PA plus PA Controller, PAC, integrated in the same module). PA modules do not require an on-chip PAC but simply an Automatic Power Control (APC) able to shape the transmission (TX) burst for the PAC within the PA module. In order to maximize the flexibility of the on-chip PA's control system, the design of programmable and versatile architectures suitable to interface both the solutions becomes then an attractive approach. This paper presents a versatile CMOS APC/PAC module which can interface most of the PAs and PA modules on the market. Two programmable operating modes can be selected: 1. PAC Mode (to interface PAs stand-alone); 2. APC Mode (to interface PA modules). The proposed architecture allows to optimize the area and save power consumption by reducing the number of operational amplifiers required by a standard approach with APC and PAC separated. The APC/PAC module features 0.6mm 2 in a 0.122m CMOS technology and consumes 9mA in PAC mode and 9502A in APC mode.

A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.
