The present invention relates to diazole derivatives of the general formulawherein A, E, R1, R2 and R3 are as defined in application and pharmaceutical compositions containing them. By stimulating a two-ADC system with a known input, the impulse response of the system is derived, and from that impulse response a finite impulse response filter is derived which corrects for mismatches between the ADCs. The gate is formed having two different conductive materials with different electric workfunctions that both significantly contribute to the overall workfunction of the gate.
