Analog System High-Level Synthesis for Energy-Efficient Reconfigurable Computing

“…This analog and mixed-signal HLS tool enables analog system design with abstraction at multiple levels of design, greatly advancing analog synthesis beyond simple blocks (e.g., current source, differential pair), creating standard analog components (e.g., amplifier, small data converter) [16][17][18][19][20][21][22]22,23]. Our approach allows for fine-grain design (transistor-level) as well as multiple higher levels of abstraction, circuit programmable at each level, enabling a wider community to use analog design tools as compared to experienced analog designers.…”

“…In contrast, analog synthesis for analog system design and analog computing is nearly non-existent. Initial efforts in analog synthesis often focused on low-level analog components, such as creating an op-amp or similar low level of circuit complexity [16][17][18][19][20]. Recent interest in analog tool development follows these directions [21][22][23], building only a few blocks (e.g., current source, differential pair) to make a small analog component (e.g., amplifier, small data converter).…”

Linear synchronization and circuit implementation of chaotic system with complete amplitude control*

“…Here in this paper we use the newest integrated circuit technique of FPAA to realize the system discussed above. An Anadigm QuadApex development board with four AN231E04 chips [41][42][43][44] was used to construct a circuit implementation of systems (1) and (2) and to experimentally verify the amplitude control and offset boosting. Each chip contains four Configurable Analog Blocks (CABs) which perform the analog processing through using the fully differentiable switched capacitor technology.…”
