An analog VLSI model of muscular contraction

We have developed analog VLSI circuits to model the behavior demonstrated by biological sarcomeres, the force generating components of muscle tissue. The circuits are based upon the mathematical description of crossbridge populations developed by A. F. Huxley (1957). We have implemented the sarcomere circuit using a standard 1.2 (mu)m process, and have demonstrated the nonlinear transient behaviors exhibited by biological muscle.
