Figure 5 is a very versatile stage. It features a bipolar swing
that is set by the output transistor’s supplies. This 3ns
delay stage is ideal for driving FET switch gates. Q1, a
gated current source, switches the Baker-clamped output
transistor, Q2. The heavy feedforward capacitor from the

Figure 6. Noninverting Voltage Gain Level Shift
LT1671 is the key to low delay, providing Q2’s base with
nearly ideal drive. This capacitor loads the LT1671’s
output transition, but Q2’s switching is clean with 3ns
delay on the rise and fall of the pulse. Figure 6 is similar to
Figure 4 except that a sink transistor has replaced the
Schottky diode. The two emitter-followers drive a power
MOSFET that switches 1A at 15V. Most of the 7ns to 9ns
delay in this stage occurs in the MOSFET and the 2N2369.
When designing level shifters, remember to use transis-
tors with fast switching times and high f
T
. To get the kind
of results shown, switching times in the nanosecond
range and an f
T
approaching 1GHz are required.
