Glossary
active high
1. A logic signal having its asserted state as the logic 1 state.
2. A logic signal having the logic 1 state as the higher voltage of the two states.
analog blocks
The basic programmable opamp circuits. These are SC (switched capacitor) and CT (continuous time) blocks.
These blocks can be interconnected to provide ADCs, DACs, multi-pole filters, gain stages, and much more.
analog-to-digital A device that changes an analog signal to a digital signal of corresponding magnitude. Typically, an ADC converts
(ADC)
a voltage to a digital number. The digital-to-analog (DAC) converter performs the reverse operation.
Application
programming
interface (API)
A series of software routines that comprise an interface between a computer application and lower level services
and functions (for example, user modules and libraries). APIs serve as building blocks for programmers that
create software applications.
asynchronous A signal whose data is acknowledged or acted upon immediately, irrespective of any clock signal.
Bandgap
reference
A stable voltage reference design that matches the positive temperature coefficient of VT with the negative
temperature coefficient of VBE, to produce a zero temperature coefficient (ideally) reference.
bandwidth
1. The frequency range of a message or information processing system measured in hertz.
2. The width of the spectral region over which an amplifier (or absorber) has substantial gain (or loss); it is
sometimes represented more specifically as, for example, full width at half maximum.
bias
1. A systematic deviation of a value from a reference value.
2. The amount by which the average of a set of values departs from a reference value.
3. The electrical, mechanical, magnetic, or other force (field) applied to a device to establish a reference level to
operate the device.
block
1. A functional unit that performs a single function, such as an oscillator.
2. A functional unit that may be configured to perform one of several functions, such as a digital PSoC block or
an analog PSoC block.
buffer
1. A storage area for data that is used to compensate for a speed difference, when transferring data from one
device to another. Usually refers to an area reserved for I/O operations, into which data is read, or from which
data is written.
2. A portion of memory set aside to store data, often before it is sent to an external device or as it is received
from an external device.
3. An amplifier used to lower the output impedance of a system.
bus
1. A named connection of nets. Bundling nets together in a bus makes it easier to route nets with similar routing
patterns.
2. A set of signals performing a common function and carrying similar data. Typically represented using vector
notation; for example, address[7:0].
3. One or more conductors that serve as a common connection for a group of related devices.
clock
The device that generates a periodic signal with a fixed frequency and duty cycle. A clock is sometimes used to
synchronize different logic blocks.
comparator
An electronic circuit that produces an output voltage or current whenever two input levels simultaneously satisfy
predetermined amplitude requirements.
compiler
A program that translates a high level language, such as C, into machine language.
