The CMOS transmission gate consists of one nMOS and one pMOS transistor, connected in parallel. The gate voltages applied to these two transistors are also set to be complementary signals. Thus, the CMOS TG operates as a bidirectional switch between the nodes A and B which is controlled by signal C. If the control signal […]

Simulation in VHDL: It describes the behaviour of the circuit in terms of input signals, the output signals, knowledge of delays. The behaviour described in terms of occurrences of events and waveforms on signals. In this mode, design description is compiled and simulated and the results are evaluated. Simulation process in VHDL is based on

1. The principle of pattern multiplication states that “the radiation pattern of an array is the product of the pattern of the individual antenna with the array pattern of isotropic point sources each located at the phase centre of the individual source.” 2. The array pattern is a function of the location of the antennas

An architecture can be written in one of three basic coding styles: (1) Dataflow (2) Behavioral (3) Structural. The difference between these styles is based on the type of concurrent statements used: A dataflow architecture uses only concurrent signal assignment statements. A behavioral architecture uses only process statements. A structural architecture uses only component instantiation

Block Diagrams: From Figure 1, we can see that in Moore’s FSM, Input goes into the combinational next state logic block whose outputs are fed to state register. The outputs of the state register are fed to combinational output logic block which gives us the outputs. Also, the output of state register is also feedback
