摘要

This paper presents a novel current-mode instrumentation amplifier (CMIA) which is based on a fully differential second-generation current conveyor (FDCCII). This circuit is innovatively adapted to both types of input signals, thus becoming uniquely versatile. As another unique quality, neither does it need well-matched active blocks nor does it require matched resistors; but it can inherently improves common-mode rejection ratio (CMRR), bandwidth (BW), power and area consumption and hence becomes an excellent matchless choice for integration. Most favorably, its CMRR is enormously (100-105 dB) improved using a current subtracting stage. The proposed CMIA is designed using TSMC 0.18 um RF CMOS 2P6M Technology and supply voltages of +/- 1V. Its pre-layout and post-layout performances both plus Monte Carlo analysis are simulated using CADENCE. In pre-layout, it achieves voltage and current CMRR magnitude-BW of 224.9 dB-7.2 KH and 104 dB-0.94 KHz, respectively, differential voltage/current gain BW of 8.42 MHz/9.02 MHz, very low consumed power of 521.7 uW, output offset of 2.23 uV and area of 63.4 um x 87 um. Exceptionally, post-layout plus Monte Carlo results are tightly close to pre-layout ones; altogether, it proves its well PVT insensitivity.
