Thanks to the advance in CMOS technology, an extensive category of applications has been migrated from traditional BJT-based processes. System-on-a-Chip (SoC) realization of digital, analog, and even high voltage devices is now a reality. To address the challenge imposed by integrating analog and high voltage devices in standard CMOS processes, this thesis aims at the design of three specific topics in particular.
With regard to the contents of the thesis, first of all, the theory of linear-in-dB automatic gain control (AGC) is discussed. In succession, a linear-in-dB variable gain amplifier (VGA) is mentioned. The implementation of a Feed-forward Output Swing Prediction AGC featuring a Prediction Parallel-Detect Single-Store Peak Detector (PDSSPD) and a High Input/Output Swing VGA is also described. Furthermore, a digitally programmable gain amplifier for a ZigBee wireless receiver is also mentioned.
In response to the advent of CMOS-compatible high voltage tolerant Bipolar-CMOS-DMOS (BCD) process, an operational amplifier for level converting operation is disclosed. A 60-V Li-ion battery charger has also been proposed, along with a novel battery charge mode, namely, the incremental charge (IC) mode. Practical issues regarding the high voltage tolerant BCD process is also briefly discussed.
Finally, a backplane transmitter featuring pre-emphasis and a receiver utilizing decisive feedback equalization (DFE) designed for CIC MorPack technology are presented. When packaged in a Leadless Ceramic Carrier (LCC) package, the transmitter can transmit up to 500 Mbps and the receiver can receive up to 125 Mbps, both through DuPont connectors without impedance matching.
