Source Problem:

Design a grounded-load v-I converter that converts a 0V to 10V input to a 4mA to 20mA output. The circuit is to be powered from +/-15V regulated supplies.

My Question:

What does it mean by a grounded-load? I am not really familiar with this term.

A boost converter has an input voltage Vin= 10 V, switching frequency fs= 100 kHz, duty ratio d=50%, load resistance RL= 20Ω, inductance 100μH, and capacitance 680 μF. If you were trying to make a boost converter enter DCM, but your load resistor could not reach Rcrit, what other controllable parameters (not including Vin) could you change to reduce the lowest value of i_L to zero? Explain your reasoning.
