Conventional ring amplifier suffers from stability problem, the problem is exacerbated when process, voltage and temperature (PVT) variations are taken into considerations. Prior works are mainly focused on stability problem, the influence of PVT on transient response were barely discussed. In this paper the influence of process variations on stability and transient response is analyzed, a process-...
Stability analysis is an important issue which should be solved at the beginning of the power amplifier design. An RC feed-back network is often adopted to improve the stability of power amplifier. Through the analysis of the RC network, a novel method to estimate the RC value is presented in this paper, which facilitates circuits design. A single stage power amplifier is designed in CMOS process...
As technology scales down, an increasing number of transistors can be integrated into a single chip but process variation becomes more serious. SRAM is one of the key components in a SoC and it occupies a large portion of the SoC. Thus, the SRAM bitcell is typically designed using very small transistors for high integration, which limits the minimum operating voltage (VCCmin) of the SoC because of...
An eight-transistor (8T) cell is proposed to improve variability tolerance and low-voltage operation in high-speed SRAM caches. While the cell itself can be designed for exceptional stability and write margins, array-level implications must also be considered to achieve a viable memory solution. These constraints can be addressed by modifying traditional 6T-SRAM techniques and conceding some design...
