The design of bandgap-based voltage references in digital CMOS raises several design difficulties, as the supply voltage is lower than the silicon bandgap in electron volts, i.e., 1.2 V. A current-mode architecture is used in order to address the main issues posed by the low supply, but ...

4.7 Capacitance Multiplier The circuit in figure 4.8(a) uses an op-amp and a small capacitor, C1, to simulate a much larger capacitor. It simulates the simple RC circuit of figure 4.8(b); the resistor R2is the same size as the resistor in the circuit being simulated (R3), but the ...

and have a basic full-scale measurement sensitivity of 200mV DC and a near-infinite input resistance. They can be made to act as multi-range DC voltmeters by simply feeding the test voltage to the module via a suitable ‘multiplier’ (resistive attenuator) network, or as multi-range DC cu...
as driven by an external 400 Hz oscillator. This modulated 400 Hz signal is fed to the op amp IC, an Amelco 809 high-performance op amp, introduced in 1967.9The IC is in a round metal can; this packaging was common back then and helped shield the op amp from noise. Finally, the IC...
