| In this dissertation, the design of configurable analog blocks for field programmable analog arrays is presented. The configurable blocks are capable of performing integration, differentiation, amplification, log, and anti-log functions. The realization of these functions depends on differential continuous-time current-mode translinear loop techniques. To maintain high frequency operation, programmability and configurability of the blocks are achieved by modifying the block's bias conditions digitally. The analog signal processing part of the blocks is designed using BJTs. To get compatibility with digital, the controlling parts of the blocks are designed using CMOS. Simulation results for the presented circuits and for examples of analog signal processing systems formed using them are also introduced. |
