Yesterday, 22:33FvM replied to a thread Shift register implementation and use of its value in PLD, SPLD, GAL, CPLD, FPGA DesignThe question makes no sense. There must be a criterion to decide if the shift register is shifted or loaded with a new value. The load signal can be...4 replies | 76 view(s) -
Yesterday, 22:24FvM replied to a thread -3db frequency of the op-amp open loop gain in Analog Integrated Circuit (IC) Design, Layout and FabricationIt's a parameter of a simplified ideal OP model with first order characteristic together with the DC gain. I think it's not so important for real OP...1 replies | 82 view(s)
