Abstract
A programmable logic array operates with a single clock signal frequency which delays a control signal allowing time for the input signals to reach steady state on the column conductors of the AND-plane before enabling an active pull-up circuit to latch those column conductors left floating by the input signals. The control signal for the active pull-up circuit of the OR-plane is also delayed allowing time for the signals on the column conductors and row conductors of the OR-plane to reach steady state and provide glitch-free output signals. The propagation paths for the control signals are made slower than the worst case data path through the AND-plane and OR-plane to eliminate race conditions.
