The present invention discloses a piezoelectric cascade resonant lamp-ignition circuit, which uses the intrinsic capacitors of a piezoelectric transformer as piezoelectric capacitors. Error concealment of the present invention can be combined with the error resilience provided by MDC to reconstruct lost frames, such that the propagated error to the following frames is reduced. A polymeric resist is printed that wicks along the reentrant profile of the gate structure. One tail portion of the terminal is located on the body segment of the spacer and the other tail portion of the terminal is embedded in the body segment of the spacer. The gaseous reducing agent is passed to the reduction catalytic converter through a pressure-relief line that includes a pressure-control valve, and, in the method, the amount is recorded by a flowmeter. All surfaces of the IC chip are coated by additional insulation layers.
